In France, a public inquiry () is a formal public consultation procedure. concerning a finalized dossier (project, plan or programme) that is sufficiently formalized in principle to be subject to environmental assessment, of which the public inquiry is a part. It involves, on the one hand, a dual obligation to provide prior information on the existence of the project and its content and, on the other hand, a register (paper / electronic) allowing the public to record their comments, which is open for a minimum period determined by law. The inquiry is conducted by an independent and impartial third party, the investigating commissioner. The prior publicity formalities are organised by the administrative authority empowered to rule on the case (usually the prefect, sometimes the mayor, or the president of an public establishment of intercommunal cooperation (EPCI), depending on the potential impacts of the project) to complete the information before the decision is made.
The public inquiry is therefore a mechanism that serves participatory democracy. It is therefore:
A provision with constitutional value, Article 17 of the 1789 Declaration of the Rights of Man and of the Citizen, proclaims that:
To legalize the declaration of public necessity, the first basis for the French public inquiry system was an imperial law of 1810 passed to guarantee respect for property rights during expropriations. The royal ordinance of May 1829 extended the measure to include a preliminary inquiry with the submission of the project in simplified form, with universal access and the collection of comments. The ordinance of February 28, 1831 required public works to undergo such a preliminary inquiry with a commission of inquiry, comment registers open for at least one month, and the commission's conclusions. A law passed in 1833 requires this preliminary inquiry (then called commodo et incommodo) for the Declaration of public utility (DUP).
A 1958 ordinance requires the inquiry and a favourable opinion before a DUP is issued. A 1959 decree, revised in 1977, specifies the characteristics of the preliminary inquiry before the DUP, intending to defend the rights of property owners before validating the administration projects. A 2014 ordinance amended this regulation in Sections L110-1 and L112-1 and R112-1 to âÂÂ24 of the Code of Expropriation for Public Utility. This inquiry, known as a "public utility inquiry," therefore formed the historical basis for public inquiries in France. It is now only a minority special case among public inquiries. It is opened and organized by the prefect of the department, and its conclusions are communicated to interested parties only upon request.
The 1983 law, known as the "Bouchardeau" law, relating to the democratization of public inquiries and environmental protection, imposed a system for informing and gathering public opinion to ensure that public and general interests were better taken into account. Its implementing decrees were signed on April 23, 1985 , and had a fairly broad scope. They were then transposed into the Environmental Code. In 1985, an initial European Union directive on the assessment of the effects of certain public and private projects on the environment required Member States to ensure "that the public concerned is allowed to express its opinion before the project is started". Amending directives were adopted to supplement it in 1997 and 2011. A 2010 law harmonized the various types of public inquiries with those of the Environmental Code, while ensuring compliance with various international legal texts. A decree issued in 2011 reformed this procedure: the scope of application was revised, the content of the investigation file was clarified, and the investigation procedure was rewritten. An order issued in 2016, followed by a decree issued in 2017, revised its scope and many elements of its procedure and process (e.g. appointment of the investigating commissioner, duration, digitization of the file submitted for investigation, the register, etc.). The entire public inquiry procedure is now contained in Articles L123-1 to âÂÂ18 and R123-1 to âÂÂ27 of the Environmental Code. For environmental permits, a law passed in 2023 added a procedure to speed up the review process, followed by an implementing decree in 2024.
Since the end of 2015, the few public inquiries that do not fall under either the code governing expropriation for public use or the environmental code have been regulated by Sections L134-1 to âÂÂ2, L134-31 to âÂÂ34 and R134-3 to âÂÂ30 of the Code of Relations between the Public and the Administration and are organized by the prefect.
Over the years, public participation in projects affecting their environment has grown; local government officials are taking participatory approaches and encouraging citizens to participate in their communities' projects. Investigating commissioners, who hold a judicial mandate, facilitate this participation and ensure the security of environmental assessment procedures, and administrative courts are often called upon by local authorities to carry out this task.
In France, starting in 2016, public inquiries tended to be classified into three main categories: environmental inquiries, public utility inquiries, and other inquiries. This classification is now obsolete: the Environmental Code. The âÂÂEnvironmental Code applies to most "construction, engineering, or development projects requiring an environmental assessment or requiring environmental authorization linked to another investigation requirement. This concerns two-thirds of public inquiries:
The public inquiry is a legal part of the process of assessing a project's environmental impact and public participation in the decision-making process. It may incorporate other procedures:
The public inquiry may concern a declaration of public interest, a project for a facility classified for environmental protection, a structure relating to water and aquatic environments, and may be subject to special provisions where applicable.
It is mandatory for projects of public interest, such as those requiring expropriation following a declaration of public utility, or those requiring the establishment of public utility easements, particularly for urban planning purposes.
Investigations before a declaration of public utility, most often with a view to expropriation, or before the creation of a public utility easement, are conducted on this basis alone if there is no environmental impact.
The so-called public utility inquiry, which concerns approximately one quarter of public inquiries, may be open to the public for only 15 days. The parcel inquiry, which is restricted to the owners of the parcels concerned (list of owners, individual notification, and Art. R131-8 of the Code of Expropriation for Public Utility), falls outside the scope of the public inquiry proper. Others may have a limited scope, such as departmental or municipal roads or rural paths.
The Environmental Code reiterates the principles that, on the one hand, "everyone has the right to access information relating to the environment held by public authorities" and, on the other hand, "everyone shall be informed of draft public decisions affecting the environment in such a way as to enable them to submit their comments, which shall be taken into consideration by the competent authority." The Charter for the Environment specifies that it is the duty of every citizen to protect their environment.
Public inquiries are one of the means used to ensure the public participation necessary for the development of certain public decisions, with the aim of "improving the quality of public decision-making and contributing to its democratic legitimacy.â . They are therefore legally required before any administrative decision that may affect either private property, particularly in the case of expropriation, or the environment. Its purpose is, respectively, to formally establish public utility before expropriation by means of a declaration of public utility or "to ensure public information and participation and to take into account the interests of third parties" so that "the comments and proposals received during the inquiry period" are "taken into consideration by the project owner and by the authority competent to make the decision.âÂÂ
It was conducted before decision-making and in a relatively impartial manner, the public inquiry therefore aims to,:
In France, a public inquiry must precede the implementation of:
Certain projects, particularly those relating to national defense, or those carried out due to a serious and immediate danger, are subject to legal exemptions from these procedures.
When a public debate is organized in advance on a major project (e.g., highway, decomissioning of a nuclear power plant, etc.), the minutes and summary of the debate must be included in the public inquiry file. In this case, the State must launch the public inquiry within five years of the publication of the minutes and summary of the public debate.
The file submitted for investigation consists of various documents,,:
In addition, there is an inquiry register for receiving comments from the public. These documents are available to the public in all locations (town hall(s)) where the inquiry is officially open, in paper format and optionally in electronic format (on a website),.
The main stages of the public inquiry process are:
Before it begins:
When the public consultation opens:
After the public inquiry has closed:
The commissioner or commission of inquiry is appointed by the president of the administrative court before the opening of the public inquiry (Sections L123-4 and R123-5 of the Environment Code). Once appointed, usually two to three months before the start of the inquiry, the commissioner or commission begins its investigations and may request the necessary documents from the petitioner or the organizing authority to prepare the information for the public. These preliminary investigations are often difficult because feasibility and impact studies are complex and often carried out by multiple parties involved in the environmental impact assessment. Impact studies are difficult to carry out because they cover many areas governed by laws and regulations (AIR, WATER, SOIL, SUB-SOIL, WILD FAUNA AND FLORA, LANDSCAPES, NEIGHBORHOOD CONVENIENCE, RATIONAL USE OF ENERGY). Its role, which is not very visible before the public inquiry is opened, requires investigating the project to fully assess the issues and impacts on the environment. In practice, petitioners or communities organizing inquiries may tend to limit access to information on sensitive projects, which can sometimes complicate the exercise of their missions.
