At any time while a ship specification has effect, any person affected by it may request the Minister to revoke the specification.

But where a person has made a request under this section in respect of a specification, no further request may be made under this section by that person or any other person in respect of that specification unless the grounds on which the further request is made are or include that there is a significant matter which has not previously been considered by the Minister.

On a request under this section the Minister must decide whether to revoke the specification or to take no action with respect to it (but see section 26(3)).

In this section—

• “the Minister”, and

• “ship specification”,

have the meaning given by section 26(1).
