The Anonymous Tip and the Search of a Flat
At 06:10 on a Tuesday, police in Liège receive an anonymous phone tip that a named man, Mr. B., keeps stolen bicycles in the cellar of his flat. Two officers go to the building, ring the bell, and Mr. B. opens the door in pyjamas. The officers say they 'just want to check the cellar.' Mr. B. replies, 'Do what you have to do, I have nothing to hide,' and steps aside. The officers search the cellar and find three bicycles matching theft reports. They then move into the living room, open a wardrobe, and find a small quantity of cannabis. Mr. B. is arrested at 07:00. No search warrant was obtained. The prosecutor asks whether the cellar and wardrobe evidence can be used.
1. Assess the lawfulness of the cellar search and the living-room search separately.

The two searches must be analysed independently because consent, if any, has a scope.
Cellar search. A search of premises normally requires a warrant from the investigating judge or a statutory exception (flagrant offence, consent, etc.). Here the officers relied on consent. For consent to be valid, it must be free, informed, and specific. Mr. B.'s words ('do what you have to do') are ambiguous. A court will ask: was he told he could refuse? Was he told the purpose and scope? Was he in a state (early morning, pyjamas, two officers at the door) that undermines free consent? The consent, if accepted, covers the cellar only, because that is what the officers announced.
Living-room search and wardrobe. Once the cellar yielded bicycles matching theft reports, the situation arguably became a flagrant offence, which can justify certain immediate measures. But opening a wardrobe in the living room goes beyond the announced scope and beyond the cellar. Unless a separate legal basis exists (flagrant offence extending to the whole dwelling, or a warrant), this search is unlawful.
Consequence. Belgian courts apply a nuanced exclusionary approach: unlawfully obtained evidence is not automatically void, but the judge weighs legality, reliability, and the seriousness of the infringement. The cellar evidence is more likely admissible (arguable consent); the cannabis from the wardrobe is more vulnerable to exclusion. The prosecution should be prepared to justify each step.
2. What should the prosecutor do at this stage, and what procedural rights does Mr. B. have?

Prosecutor's assessment.
- Verify the file. Obtain the officers' written report (procès-verbal), noting exactly what was said about consent, the time, and the sequence of rooms searched.
- Characterise the offences. The bicycles support theft or handling stolen goods; the cannabis supports a drugs offence. The two may be joined but the evidentiary basis differs.
- Decide on admissibility strategy. The prosecutor should not assume automatic exclusion; Belgian law allows the judge to weigh the infringement. But the prosecutor must disclose the circumstances of the search, because concealing them would taint the file.
- Consider further investigation. A warrant might now be sought to secure the flat if needed; the bicycles should be inventoried and returned to owners where possible.
Mr. B.'s rights.
- Right to be informed of the charges promptly and in a language he understands.
- Right to a lawyer before and during police interrogation; right to silence; right not to incriminate himself.
- Right to access the case file and to challenge the lawfulness of the search before the investigating judge or the trial court.
- Right to have the procès-verbal and the consent issue tested in adversarial proceedings.
- If detained, the strict time limits for bringing him before the investigating judge must be respected; any delay is a ground for release.
The prosecutor should also consider whether disciplinary or internal review of the officers' conduct is warranted, independently of the criminal case.
