Every reference under section 41E above shall specify a period (not longer than six months beginning with the date of the reference) within which a report on the reference is to be made.
A report of the CMA on a reference under section 41E above shall not have effect (in particular for the purposes of section 41D(5) above) unless the report is made before the end of the period specified in the reference or such further period (if any) as may be allowed by the Authority under subsection (3) below.
The Authority may, if it has received representations on the subject from the CMA and is satisfied that there are special reasons why the report cannot be made within the period specified in the reference, extend that period by no more than six months.
No more than one extension is possible under subsection (3) above in relation to the same reference.
The Authority shall publish an extension under subsection (3) above in such manner as it considers appropriate for the purpose of bringing it to the attention of persons likely to be affected by it.
