4.1
Regulation XI-2/9.1.1 provides
that every ship to which chapter XI-2 applies
is subject to control when in a port of another Contracting Government
by duly authorised officers, who may be the same as those carrying
out the functions of regulation I/19.
Such control shall be limited to verifying that there is onboard a
valid International Ship Security Certificate (ISSC) or a valid Interim
International Ships Security Certificate (Interim ISSC) issued under
the provisions of part A of the ISPS
Code, which if valid shall be accepted, unless there are clear grounds
for believing that the ship is not in compliance with the requirements
of chapter XI-2 or part A of the ISPS Code.
4.2 Therefore, in cases where no clear grounds
are established before the ship enters port, the ship may still be
subject to control under the provisions of regulation
XI-2/9.1.1. This may be carried out in conjunction with the
port State control inspections conducted under the provisions of regulation I/19 and of resolution A.787(19) entitled Procedures for Port
State Control, as amended by resolution A.881(21) entitled Amendments
to the Procedures for Port State Control.
