Costs order

28 November 2017: The CMA has announced its costs order in 2 leased line price control appeals. A non-confidential version of the determination is available below.

Final determination

10 April 2017: The CMA has published its final determination in 2 leased line price control appeals.

Appeal group appointed

17 November 2016: The CMA has appointed a group of panel members to determine the appeals. Alasdair Smith (Chair), Rosalind Hedley-Miller, Michael Hutchings and Graham Sharp.

Disclosure of interest

Graham Sharp anticipates inheriting BT shares (with a value of less than £5,000) which may or may not occur during the proceedings. The CMA is satisfied that this matter will not prejudice the ability of the appeal group to discharge its functions in an independent and impartial manner.

Case referred

17 November 2016: The Competition Appeal Tribunal (CAT) has referred to the CMA 2 telecoms appeals concerning the amount BT can charge other providers for purchasing leased line services.

CityFibre Infrastructure Holdings plc (CityFibre) and TalkTalk Telecom Group Plc (TalkTalk) both appealed to the CAT following the Office of Communications (Ofcom’s) final decision in its Business Connectivity Market Review in April this year.

Under the 2003 Communications Act, if decisions by Ofcom are appealed to the CAT and include a price control matter, then this matter must be referred to the CMA for determination. Both parties have therefore sought a reference to the CMA of the price control matters in their respective appeals.
