Article 9 Waiver
United Kingdom
Without prejudice to national law requiring the mandatory presence or assistance of a lawyer, Member States shall ensure that, in relation to any waiver of a right referred to in Articles 3 and 10:
the suspect or accused person has been provided, orally or in writing, with clear and sufficient information in simple and understandable language about the content of the right concerned and the possible consequences of waiving it; and
the waiver is given voluntarily and unequivocally.
The waiver, which can be made in writing or orally, shall be noted, as well as the circumstances under which the waiver was given, using the recording procedure in accordance with the law of the Member State concerned.
Member States shall ensure that suspects or accused persons may revoke a waiver subsequently at any point during the criminal proceedings and that they are informed about that possibility. Such a revocation shall have effect from the moment it is made.
