The CMA shall, subject to subsections (2) and (3), make a reference to its chair for the constitution of a group under Schedule 4 to the Enterprise and Regulatory Reform Act 2013 if the CMA believes that it is or may be the case that—
a
arrangements are in progress or in contemplation which, if carried into effect, will result in the creation of a relevant merger situation; and
b
the creation of that situation may be expected to result in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services.
1A
The CMA must make a reference to its chair for the constitution of a group under Schedule 4 to the Enterprise and Regulatory Reform Act 2013 if the CMA has decided, under
section 34ZF
(3)
, to accept a fast-track reference request.
2
The CMA may decide not to make a reference under subsection (1) if it believes that—
a
the market concerned is not, or the markets concerned are not, of sufficient importance to justify the making of a reference ...;
b
the arrangements concerned are not sufficiently far advanced, or are not sufficiently likely to proceed, to justify the making of a reference ...; or
c
any relevant customer benefits in relation to the creation of the relevant merger situation concerned outweigh the substantial lessening of competition concerned and any adverse effects of the substantial lessening of competition concerned.
3
No reference shall be made under subsection (1) if—
za
the period within which the CMA is required by section 34ZA to decide whether the duty to make the reference applies has expired without such a decision having been made;
a
the making of the reference is prevented by section . . . 74(1) ... or paragraph 4 of Schedule 7;
b
the CMA is considering whether to accept undertakings under section 73 instead of making such a reference;
c
the arrangements concerned are being, or have been, dealt with in connection with a reference made under section 22 ...; or
d
a notice under section 42(2) is in force in relation to the matter or the matter to which such a notice relates has been finally determined under Chapter 2 otherwise than in circumstances in which a notice is then given to the CMA under section 56(1); or
