C5.2.3.p. Does a change of the RO affect the validity of already issued certificates?

Regulation 5.1.1, paragraph 3, provides that:

3. In establishing an effective system for the inspection and certification of maritime labour conditions, a Member may, where appropriate, authorize public institutions or other organizations (including those of another Member, if the latter agrees) which it recognizes as competent and independent to carry out inspections or to issue certificates or to do both. In all cases, the Member shall remain fully responsible for the inspection and certification of the working and living conditions of the seafarers concerned on ships that fly its flag.

Since the flag State remains fully responsible for the inspection and certification irrespective of the delegation [see C5.2.1.b.] a change of RO would not affect the validity of already issued certificates.
