176Provision of supplementary information
Where by virtue of this Act—
(a)any application or notice under any enactment is required to be supplemented by such information as the person to whom the application is made or on whom the notice is served may require; and
(b)that person is required to do anything within a specified period after the application or notice is made or served,
the failure to provide the information shall not invalidate the application or notice but, if the requirement to provide the information was made at such a time before the end of the period as gave the applicant or the person serving the notice a reasonable opportunity to provide it within the period, the person who required the information shall be entitled to delay doing that thing until a reasonable time after the required information is provided.
