Chapter 2. Concession of Public Service: A Jurisprudential Analysis
The concept of “public service concession” occupies a pivotal position within administrative law, representing a sophisticated mechanism through which public authorities delegate the operation of essential services to private entities. This chapter provides an in-depth jurisprudential analysis of the provisions governing public service concessions as stipulated in the Civil Code, elucidating the intricate balance between the public interest, administrative control, and the contractual rights of the private grantee. The inherent singularity of these agreements necessitates a legal framework distinct from conventional private contracts, a distinction predicated upon the continuous public purpose intrinsic to the delegated activity.
Article 3207: Definitional Parameters of Public Service and Concession
This foundational article furnishes a dual definitional exposition, commencing with “public service” and subsequently addressing its “concession.” (1) The definition of “public service” is characterized by its functional and teleological dimensions. It encompasses “any activity which a public community has decided to perform for the reason that it has deemed it to be necessary in the general interest and considered that private initiative was inadequate for carrying it out.” This definition underscores two critical components: * Public Interest Imperative: The activity must be demonstrably essential for the collective welfare of the community. This criterion highlights the state’s fundamental responsibility to ensure the provision of indispensable services. * Inadequacy of Private Sector Engagement: This criterion suggests that governmental intervention is warranted when market forces or purely private endeavors prove insufficient or disinclined to provide the service at the requisite quality, scale, or level of accessibility. This frequently pertains to sectors such as infrastructure, public utilities, or social services, where substantial capital investment, long-term commitment, or universal access mandates state involvement. The concept of “public service” (service public), a cornerstone of continental administrative law, serves to differentiate activities undertaken for the collective good from purely private commercial undertakings.
(2) The “concession of a public service” is subsequently defined as a specific contractual modality: “whereby a person, the grantee, binds himself in favour of an administrative authority to run a public service getting a remuneration therefore by means of fees received on the use thereof.” This definition elucidates several salient features of a concession: * Contractual Formalism: It constitutes a formal agreement, thereby distinguishing it from unilateral administrative acts. * Delegation of Operational Responsibility: The administrative authority delegates the running (operation) of the service, rather than its ownership or ultimate accountability. The state retains regulatory oversight and ultimate control over the public service. * Grantee’s Remuneration Structure: Critically, the grantee’s remuneration is derived “by means of fees received on the use thereof” from the service’s end-users, as opposed to direct payment from the administrative authority (a characteristic typically associated with public works or supply contracts). This arrangement partially transfers financial risk to the grantee and the users, rendering the concessionaire dependent upon the commercial success of the service. This article, therefore, establishes the conceptual framework for understanding concessions as a form of delegated public management, wherein private capital and expertise are leveraged for public benefit, subject to rigorous administrative oversight.
Article 3208: Administrative Authorities’ Prerogative of Control – 1. Principle
This article articulates the fundamental and continuous prerogative of administrative authorities to oversee the performance of a public service concession. (1) The “administrative authority responsible for the good running of the public service may at any time supervise the performance of the contract.” This principle of continuous administrative control (pouvoir de contrôle) is inherent in administrative concessions, reflecting the state’s enduring responsibility for the public service, irrespective of delegation. It constitutes a manifestation of the pervasive public interest that informs the entirety of the contractual relationship. (2) Correspondingly, the grantee is obligated to “render an account of his management to such authority and and give it the necessary facilities for exercising its control.” This imposes a duty of transparency and cooperation upon the concessionaire, ensuring that the administrative authority possesses access to all requisite information for monitoring the service’s quality, efficiency, and adherence to public policy objectives.
Article 3209: 2. Regulatory Framework
(1) This article mandates that the control of the grantee “shall be organized in accordance with the provisions of regulations and with the contractual provisions made by the parties.” This suggests a dual source for control mechanisms: general administrative regulations (e.g., public procurement legislation, sector-specific regulatory instruments) and specific clauses embedded within the concession contract itself. This dual approach permits both standardized oversight and tailored control mechanisms for unique concessionary arrangements. (2) Importantly, it stipulates that the provisions of the subsequent articles (3210 and 3211) “shall apply in addition, notwithstanding any stipulation to the contrary.” This establishes these subsequent articles as mandatory, non-derogable principles of administrative control, reflecting their foundational significance to the integrity of public service concessions.
Article 3210: 3. Limitations on Control
This article precisely delineates the critical boundaries of administrative control, ensuring a co oversight does not fundamentally alter the intrinsic nature of the concession. (1) The exercise of control “may not be such as to alter the nature of such concession and to transform it in fact in a direct exploitation by the administrative authorities.” This serves as a vital safeguard against de facto nationalization or unduly extensive administrative interference, whichncessi effectivelyon is th fundamentally altervate intrinsic party operate concession entails the private party operating the service at its own risk and initiative, albeit under public oversight. Overly intrusive control could effectively convert the concession into a direct public management arrangement, thereby undermining the established contractual framework. (2) Furthermore, administrative authorities “may not subject a whole section of thels.” T entails the private party operatingm stifling the grantegeriarantee’s operational autonomy by requiring prior authorization for every significant decision, an imposition that would effectively transfer managerial responsibility back to the state. (3) “Unless otherwise provided, the grantee may freely determine the manner in which he will perform the contract.” This reinforces the grantee’s operational freedom and managerial discretion, acknowledging that the delegation aims to leverage private sector efficiency and innovation. These limitations on control are indispensable for preserving the contractual equilibriument and the regulation of public order.” This p equilibrium and the distinct identityc i a concession as a delegated, rather than directly managed,nterest service.
Article 3211: 4. Contractual Interpretation
(1) This article addresses the interpretation of contractual provisions in lightth,ons pertaining to control and public order. It stipulates that contractual provisions “may not be interpreted as being an obstacle to the application of new regulations concerning the control of the management and the regulation of public order.” This principle ensures that the public interest, as articulated through new regulatory measures, may take precedence over specific contractual terms, particularly in matters concerning public safety, health, or fundamental administrative oversight. It constitutes, which wou constitutes a manifestation of the pouvoir de police administrative (administrative policing power)nfrihts. state’s inherent right to regulate for the public welfare.

This ensures that contractual enforcement remains within the confines of the specific agreement and applicable administrative law, rather than being disguised as broader public policy.
Article 3212: Contractual Modification of Prices or Tariffs – 1. Principle
This article introduces the concept of mechanisms for the adjustment of prices and tariffs within concession contracts. It permits the inclusion of contractual provisions stipulating that “the prices or tariffs mentionedial typ contract shall be modified, should a specified economic change take place.” This acknowledges the long-term nature of many concessions and the necessity of adapting financial terms to evolving economic realities, thereby ensuring the economic viability of the service for the grantee while simultaneously safeguarding users from arbitrary price increases.
Article 3213: 2. Variation Clauses
(1) This sub-article defines “variation clauses” as those wherein changes to prices oruse.” Th occur “automatically in accordance withis p in proportion to variations occurring in therovides di certain materials, commodities or services.” These typically manifest as indexation clauses, linking the concession fees to objective economic indicators (e.g., inflation rates, raw material costs, labor costs). The objective of such clauses is to maintain the economic equilibrium of the contract by automatically adjusting revenues to reflect fluctuations in input costs. (2) In instances of dispute concerning the application of a variation formula, the court is empowered to “fix the new tariffs and prices resulting from the application of the variation clause.” This provision establishes a judicial mechanism foro thoption implementationonal clause to the ct.” calculation and implementation of these automatic adjustments.
Article 3214: 3. Revision Clauses
(1) This sub-article defines “revision clauses” as possessing a less precise character than variation clauses. They stipulate that prices and tariffs “shall be revised where economic circumstances change considerably, without establishing precisely the bases of such revision.” This implies a qualitative threshold for revision, triggered by significant, rather than merely automatic, economic shifts. (2) Upon the occurrence of the specified conditions for revision, the parties are obligated to “negotiate theThis emph of an additional clause to the contract.” This emphasizes a consensual approach to re-establishing contractual balance. (3) “In default of agreement between them, the court may fix a tariff which ensures an equitable remuneration to the grantee.” This provision constitutes a crucial judicial safety net, enablinged tariff that ensures the grantee receives fair compensation, preventing the cont merelyract from becom therebying economicall contract from becoming economically unviable due to unforeseen economic changes. This embodies the principle of maintaining the financial equilibriumaus emp concession.
Article 3215: 4. Enforcement of Clauses
(1) This article specifies the effective date for invoking variation and revision clauses: “as from the datenstet, tender,” unless otherwise stipulated. This ensures that the economic conditions prevailing at the time of the bid submission serve as the baseline for subsequent adjustments. (2) However, the grantee “may not invoke such clauses on account of variations which take place after the expiry of the normal time laid down for the performance of his obligations… unless an extension of such time has been expressly granted.” This provision precludes a grantee from benefiting from delays attributable to their own non-performance by claiming adjustments for economic changes occurring during such periods of delay. It thereby incentivizes the timely completion of the contract.
Article 3216: Unilateral Modificationse s Contract – 1. Principle
This article re-emphasizes and specifiesuch administrative authority’spiry of the normal time laid down for the performance of his obligations… unless an extension of such time has been expressly granted.” This provision precludes a grantee from benefiting from delays attributable to their own non-performance by claiming adjustments for economic changes occurring during such periods of delay.cem therebyents, or high theer standards of public service. (2) They may also “impose on the grantee m standardsodi public service. (2) They may also “impose onfica grantee modifications of the organization of the service provided in the act of concession or in the specifications.” This extends the scope of this power to encompass structural and operational aspects of the concession. (3) Crucially, “Any stipulation to the contrary shall be of no effect.” This renders the jus variandi a mandatory and non-derogable power, reflecting its fundamental importance to the state’s capacity to ensure the optimal functioning of public services.
Article 3217: 2. Modifiable Clauses
(1) This article clarifies the scope of thetions of the organization of the service provided in the act of concession or in the specifica potent jus variandi (right to vary) within the context of concessions. (1) The administr thereby safeguarding fundamentalf, impose on the grantee all the intrinsic obligations which they think fit from arbitrary alteration. (2) Specifically, administrative authorities “may in particular increase or reduce the extent of the service to be operated by the grantee or impose upon him an extension of the service.” This allows for adaptation to changing demand or public policy, such as expanding the service area or augmenting operational capacity.
Article 3218: 3. Limitations on Modifications
This article imposes critical limitations upon the jus variandi, preventing its abuse and preserving the fundamental nature of the concession agreement. (1)lly, administrative authorities “may in parcrease or reduce the exten organization of the service as would actually modify the nature or object of the contract.” This provision precludes the administration from fundamentally transforming the concession into an arrangement substantively different from that originally agreed upon. article imposes critical limits on the jus variandi, preventing its abuse and safeguarding the fundame provisionntal natuf the concession thereby safeguardi governmentalng) Administrative authorities “may not impose intrinsic therebysuch modifications in the organi from arbitrary alteration.ice as would actually modify the nature or object of the contract.” This prevents the administration from fundamentally transforming the concession into something entirely different from what was originally agreed. (2) In particular, they “may not substitute a manant under state control for the concession.” This prevents the de facto nationalization or direct takeover of the service through excessive modifications, reinforcing the distinction between dele limitations are indispensable public management. (3) Furthermore, they may not “order the grantee to manage a service different to that Non-Modifiablewhich hage a really new service or a service which obviously surpasses the potentialities of the grantee.” This ensures that the modifications remain within the scope of the original concession and provision serves to protect the grantee’s economic viability and profitability, factors thatndamentally altered obligations. These limits are essential for maintaining the contractual equilibrium and the viability of the private enterprise.
Article 3219: 4. Clauses Which May Noe Modi constitutesfied
(1) This article identifies core financial aspects that administrati revocation would fundamentally undermine the agreement. (3) However, a crucial exception is recognized:s to the grantee.” This protects the grantee’s economic viability and profitability, which are essential for attracting private investment in public services. (2) In particular, they “may not cause prejudice to any privilege of exclusivity accorded to the grantee.” Exclusivity is often a key incentive for private investment in concessions, and its unilateral removal would fundamentally undermi thene the agreement (e.g., affordable services) with the grantee’s economic rights.
Article 3220: 5. Compensation Payable to Grantee
(1) This article reiterates the entitlement to compensation when administrative authorities exercise their prerogative of unilateral modification. The grantee “shall be entitled to compensation for the loss sustained by him through such modification.” (2) The compensation “shall be equal to the increase of the charge imposed upon him by the administrative authorities.” This implies that the compensation is intended 5.

This article addresses the grantee’s discretion in establishing user fees. Where the concession agreement authorizes the grantee to collect fees “within the limits of a maximum tariff fixed by the act of concession,” the grantee “may freely fix the fees within the limits of such maximum.” This grants the concessionaire a degree of commercial flexibility to optimize revenue within a publicly establisheds with Us therebyers – 1. Fixing of Tariffs
This article addresses the grantee’s discret Tariffion in settin. Where the concession agree established by the authorities are modified, the “new conditions or tariffs shall apply immediately, but without retroactive effect, to the contracts which are still in force between the grantee and the users.” This ensures that new regulations take effect promptly for ongoing service provision, while precluding retroactive alteration ofrdability for users.

When conditions Binding Nature ofor tariffs the authorities are modified, the “new cond character of the concession: the grantee “may not, by a particular agreement concluded with a user, depart from the general rules of the service fixed by the act of concession or by the specifications.” This provision precludes the grantee from entering into individualized agreements pastns or oblig wouldations, respecting legal certainty.

Conce therebyssion Bin equitablerticle reinforce alls the public service nature of the concession: the grantee “may not, by a particular agreement concluded with a user, depart from the general rules of the service fixed by the act of concession or by the specifications.” This prevents the grantee from entering into special deals with individual users that undermine the uniform appli receive equal treatment, thereby preventing arbitrary favoritism or disadvantage. This constitutes a core principle of public service, frequently referred to as the principle of equality before public service. (2) “The tariffs of service may not contain differentiations between categories of users unless such differentiations are in respect of different conditions of users in relation to the public service.” This permits justified differentiation (e.g., varying rates for residential versus industrial electricity consumption, or peak versus off-peak transport fares), provided such distinctions are predicated upon objective differences in service conditions or costs, rather than arbitrary discrimination. (3) This principle of equality extends even to “Industrial and commercial public services,” notwithstanding that their operation may be conducted “according to the rules of private law.” This underscores that even when a public service adopts commercial management principles, its underlying public purpose mandates adherence to fundamental administrative law principles, including equality.
Article 3225: 5. Relations between Users and Grantee
(1) This article mandates that “Mistakes or irregularities committed in giving effect to the conditions or to the tariffs shall be made good.” This ensures that users are protected from errors in billing or service provision and possess a right to rectification. (2) It establishes a short prescription period: an action by a user to claim restitution of an unduly collected sum must be instituted “within one year from the day of the payment unduly made.” (3) Similarly, an action by the grantee to claim a supplement of the price must be instituted “within one year from the day when the incorrect payment has been made.” These abbreviated claim restitution of an un theduly collected sum must be instituted “within one year fr Non-Representation ofom theent unduly made.” (3) Similarly, an action by the grantee to claim a supplement of the price must be instituted “within one year from the day when the incorrect payment has been made.” These short limitation periods promote prompt resolution of billing disputes.
Article 3226: 6. Users Not Represented by Administrative Authorities
This article clarifies that administrative authorities “may not claim compensation from the grantee by reason of the loss caused by him to the users of the service by the non-observance on his part of the provisions of the concession.” This means that the administrative authority cannot act as a proxy for individual users to claim damages. Users must pursue their own claims directly against the grantee for losses incurred due to the grantee’s non-compliance with concession terms. This maintains the direct contractual relationship between the user and the grantee for service-related claims.
Article 3227: Duration of Concession
(1) The “duration of the concession shall be fixed by the contract.” This emphasizes the importance of a clear, agreed-upon term for these long-term agreements. (2) It imposes a maximum duration: “It may not exceed sixty years.” This limit aims to prevent excessively long concessions that could stifle competition, hinder future policy changes, or create perpetual monopolies. (3) “Unless otherwise expressly provided, the concession shall be deemed to have been made for a period of seven years.” This provides a default duration for cases where the contract is silent, ensuring legal certainty.
Article 3228: Extension of Concession
(1) This article provides for “tacit renewal” of a concession “where the intention to terminate it has not been signified by one of the parties to the other two years before the date when… it is to come to an end.” This mechanism promotes continuity of public service by automatically extending the concession if neither party expresses a desire to terminate within a specified notice period. (2) In such a case, the concession is extended “for a period of seven years or for such shorter period as the parties may have originally fixed.” This sets a default renewal term, again promoting certainty.
Article 3229: Winding Up of Concession – 1. Principle
(1) This article establishes that the “termination of the concession… shall entail its winding up and the settlement of accounts between the grantee and the authorities.” This is a necessary consequence of the end of the contractual relationship, involving the transfer of assets and financial reconciliation. (2) The winding up “shall be made in accordance with the stipulations of the specifications.” This prioritizes specific contractual provisions for the handover process. (3) “Failing such stipulations, it shall be made in accordance with the provisions of the following Articles.” This provides default rules for winding up when the contract is silent.
Article 3230: 2. Obligations of Grantee
(1) The grantee is obligated to provide “all the information necessary to facilitate the taking back and exploitation of the concession” by the authorities. This ensures a smooth transition and continuity of public service. (2) The grantee must “deliver to the authorities in a good condition all the works and materials of the concession which are to be returned gratuitously… or which such authorities are entitled to take back against compensation.” This specifies the physical handover of assets.
Article 3231: 3. Things to be Returned
(1) This article introduces the principle of retour gratuit (gratuitous return) for “immovable property included in the concession.” This means that land, buildings, and fixed infrastructure developed for the concession typically revert to the administrative authority without compensation upon termination, as they are considered integral to the public domain. (2) The same principle applies to “movable property the return of which… without compensation has been expressly provided in the specifications.” This allows for contractual stipulation of gratuitous return for specific movable assets.
Article 3232: 4. Things Which May Be Taken Back
(1) Administrative authorities “may take back against compensation any other thing used in the exploitation of the concession.” This covers movable assets not subject to gratuitous return, allowing the authorities to acquire them if needed for continued service. (2) However, authorities “shall not be bound to take back the things used in the exploitation of the concession unless such obligation has been imposed upon them by the specifications.” This protects the administration from being forced to acquire unwanted assets.
Article 3233: 5. Amount of Compensation
(1) Disputes over compensation (under Article 3232) are to be resolved by “arbitrators appointed by the parties or, failing such, by the court.” This provides a dispute resolution mechanism. (2) If the cost of the property can be established, compensation is fixed on that “basis from which a deduction shall, where appropriate, be made in respect of depreciation due to deterioration or to wear and tear.” This aims for fair market value, accounting for asset depreciation. (3) If the cost cannot be established, compensation is fixed “having regard to the value of the things at the time when they are taken back.” This provides a fallback valuation method.
Article 3234: 6. Contracts
(1) The grantee must inform the authorities of “all the contracts which are in course and which concern the concession.” This ensures transparency regarding ongoing third-party agreements. (2) The authorities “shall take the place of the grantee in all such contracts unless, within one month from having been informed… they inform the grantee and the party who has contracted with the latter of their intention to repudiate it.” This allows for continuity of essential sub-contracts but also provides the administration with the option to terminate those it deems undesirable. (3) “Unless otherwise expressly provided in the contract, the grantee shall not be liable to a contracting party for such repudiation.” This protects the original grantee from liability for contracts repudiated by the administrative authority.
Article 3235: 7. Securities
After accounts are settled, “the securities given by the latter shall be returned to him and the sureties which be has given be released.” This ensures that financial guarantees provided by the grantee are released once all obligations are discharged.
Article 3236: Redemption of Concession (Rachat) – 1. Principle
(1) “Redemption” (rachat) is a specific form of unilateral termination by administrative authorities: it is a “decision whereby the administrative authorities put an end to the concession before the expiration of its time notwithstanding that the grantee has committed no fault.” This distinguishes it from termination for fault. (2) The administrative authorities “may at any time redeem the concession for the purpose of abolishing or reorganizing the public service.” This is a discretionary power exercised solely in the public interest, allowing the state to regain direct control or restructure the service. (3) Crucially, they “may not redeem it in order to replace the grantee by another grantee.” This prevents the rachat power from being used as a means to arbitrarily switch concessionaires, ensuring it is reserved for genuine public policy shifts, not for mere dissatisfaction with the current operator.
Article 3237: 2. Effect of Redemption
(1) A redeemed concession “shall be wound up in accordance with the provisions of the preceding Articles.” This means the general winding-up rules apply. (2) However, the grantee “shall be compensated for all the loss caused to him by the redemption and in particular for the loss which is caused to him by the making over to the authorities of property which he has not yet had the time to amortise.” This ensures full indemnification, including for unrecovered investments. (3) An “equitable compensation may be granted to him having regard to the profit which he could reasonably have expected and of which he has been deprived by the redemption.” This is a significant aspect of rachat compensation, as it explicitly includes lost future profits, making it a more comprehensive form of indemnification than for ordinary unilateral modification. This high level of compensation reflects the extraordinary nature of rachat and its impact on the grantee’s long-term business plan.
Article 3238: Loss of Right of Grantee (Déchéance) – 1. When Ordered
(1) “Loss of right” (déchéance) is a severe sanction: it “may be ordered where he has committed a fault of a special gravity.” This signifies a termination for grave contractual breach by the grantee. (2) Typically, déchéance “may only be ordered by the court, unless an express stipulation to the contrary in the act of concession has gives such right to the administrative authorities.” This emphasizes judicial oversight for such a drastic measure, though contractual provisions can delegate this power to the administration in specific cases.
Article 3239: 2. Effect of Loss of Right
(1) “Loss of right shall entail a definitive cancellation of the contract.” This is a permanent termination due to the grantee’s fundamental breach. (2) The grantee who has lost his right “shall bear the onerous consequences of the transactions having the object of ensuring the continuation of the public service.” This means the defaulting grantee is liable for the costs incurred by the administration to ensure the service continues, reflecting the punitive nature of déchéance.
Article 3240: 3. Rights of Grantee Having Lost His Right
(1) The concession “shall be allocated by tender at the risk of the grantee who has lost his right.” This means any financial shortfall from the new tender process (e.g., if the new concessionaire offers less favorable terms) is borne by the defaulting grantee. (2) The grantee who has lost his right “shall receive from the new grantee the price fixed by the allocation, which sum shall take the place of all his rights on the concession.” This provides a mechanism for the defaulting grantee to recover some value from the assets or remaining term of the concession, but it is contingent on the new allocation and serves as their sole claim.
Article 3241: Sequestration – 1. Conditions
(1) “Sequestration” is a temporary measure: it “may be ordered in the case of total or partial interruption of the service due to the default, incompetence or incapacity of the grantee.” This allows the administration to intervene to ensure service continuity in crisis situations. (2) It may also be ordered “in the absence of any fault of the grantee… from the time when it appears that the grantee is unable to operate the service.” This provides for intervention even in no-fault situations (e.g., financial distress of the grantee) to prevent service disruption.
Article 3242: 2. Effect of Sequestration
(1) Sequestration “shall temporarily deprive the grantee of the exercise of the rights which he held under the concession.” This is a temporary suspension of the grantee’s operational control. (2) If sequestration is a sanction for “fault of the grantee,” the service is managed “at the expense and risk of the grantee, by the authorities or by a manager appointed by them.” This means the defaulting grantee bears the costs of the administrative takeover. (3) “In other cases” (no fault), “the expenses of the sequestration shall be borne by the authorities.” This ensures that the administration covers the costs of intervention when the grantee is not at fault.
Article 3243: Power of the Court
(1) This article grants the court a crucial oversight role: it “may cancel the sanctions of coercion or dissolution, such as measures of sequestration, state control, loss of right or termination, taken by the administrative authorities against the grantee of the public service.” This provides a judicial check on administrative power, ensuring that severe sanctions are applied lawfully and proportionately. (2) The court “may order the authorities to pay compensation for the damage caused to the grantee in consequence of sanctions applied by such authorities contrary to the law.” This provides a remedy for grantees who suffer harm due to unlawful administrative actions, reinforcing the principle of administrative legality and accountability.
In summation, Chapter 2 of Title XIX meticulously constructs a specialized legal framework for public service concessions. It acknowledges the inherent tension between the contractual autonomy of the private grantee and the paramount public interest in the continuous, efficient, and equitable provision of essential services. The provisions delineate a robust system of administrative control, mechanisms for contractual adaptation to changing circumstances (including the unique doctrines of jus variandi and imprévision), and a graduated scale of administrative sanctions and remedies, all subject to significant judicial oversight. This complex legal architecture aims to facilitate effective public-private partnerships while safeguarding the public welfare that forms the ultimate raison d’être of public service concessions.
