For those detained on administrative cases, nothing has changed: as before, they have the right to call their loved ones “as soon as possible,” but no later than three hours from the moment of detention. In addition, at the request of the detainee, police officers are obliged to inform his lawyer where he is, as well as the place of work or study of the detainee. De facto, the police, as a rule, do not confiscate mobile phones from detainees under administrative procedure - so the right to make a call is limited only by the charge of the phone.
The online publication Meduza, together with OVD-Info, has prepared a certificate on how to behave when detained.
