The Provisional Mayor's Detention Order
A small Walloon municipality of 4,200 inhabitants has a mayor who is on sick leave for three months. The first alderman, Ms. L., is designated to replace him. During a summer festival, two groups clash and police detain a 19-year-old man, Mr. D., at 22:40 for public drunkenness and insults to officers. At 23:15 Ms. L., acting as mayor, signs an administrative detention order keeping Mr. D. in the municipal holding cell until 8:00 the next morning, citing a 2019 local police regulation that says 'the acting mayor may order detention of any person disturbing public order for up to twelve hours.' Mr. D.'s lawyer arrives at 23:50 and argues the order is unlawful. The municipal council never approved the 2019 regulation under any formal procedure; it was a circular from the previous mayor to the local police. A criminal file for the insults is opened separately.
1. Is the detention order valid? Identify the legal character of the 2019 'regulation' and the competence of the acting mayor.
Read the worked answer
The order is almost certainly invalid. Three layers must be separated.
1. Nature of the 2019 instrument. A circular from a mayor to the local police is an internal service instruction, not a municipal regulation. Municipal regulations require a formal decision by the municipal council (or, for police regulations, the council acting under the New Municipal Law), publication, and a legal basis. An internal circular cannot create a power to deprive someone of liberty.
2. Competence to restrict liberty. Administrative detention restricting individual liberty must rest on a statute or a regulation adopted on a statutory basis. A mayor's police powers under the New Municipal Law allow measures necessary for public order, but they do not create a free-standing power to detain a person in a cell for hours. Deprivation of liberty is a matter reserved to the legislature and to judicial authority; the ordinary courts and the criminal procedure code govern arrests.
3. The acting mayor's status. Ms. L. exercises the mayor's powers by substitution, but substitution transfers only the powers the mayor actually holds. It cannot enlarge them. If the underlying instrument is void, the substituted authority is void too.
Conclusion: the order lacks a valid legal basis, is disproportionate, and should be annulled by the administrative court; Mr. D. should be released and the criminal file handled separately through ordinary criminal procedure.
2. If Mr. D. seeks annulment before the Council of State, what procedural obstacles should his lawyer anticipate, and what interim route exists?

Admissibility hurdles.
- Time limit. The annulment action must be brought within 60 days of notification or publication of the contested act. Because the order was handed to Mr. D. at 23:15, the clock runs from notification.
- Interest. Mr. D. has a direct, personal, actual interest because he was deprived of liberty; that is easy to establish.
- Exhaustion of administrative remedies. Belgian law generally does not require prior administrative appeal before the Council of State, but the lawyer should check whether the New Municipal Law provides a specific supervisory route (provincial governor, minister) that affects the act's status.
- Act of government / internal measure. The lawyer must frame the challenge against the individual detention order, not the circular, because internal instructions are not generally annulable acts.
Interim relief. The lawyer should file a request for suspension (and, if possible, annulment) with the Council of State's administrative litigation section, invoking urgency and a serious argument (the moyen sérieux). Because the detention expires at 8:00, the practical remedy is immediate release through a habeas-style application to the ordinary courts or the investigating judge, not the Council of State, whose suspension procedure cannot realistically operate overnight. The lawyer should also notify the public prosecutor, since an unlawful deprivation of liberty may trigger criminal and disciplinary consequences.
