He advises and represents clients in all types of competition disputes before the UK courts, including appeals, follow-on damages actions and commercial disputes raising competition issues. He also has experience of international competition disputes, including multi-jurisdictional cartel litigation and the competition aspects of international arbitrations.

He has also negotiated and drafted national security undertakings under the Enterprise Act 2002.

Matthew has broad experience of advising clients from a broad range of industries on ensuring that their agreements and commercial practices comply with the Competition Act 1998 and Articles 101 and 102 TFEU. He advises on the application of “block exemptions”, where available, including for vertical agreements, motor vehicle distribution, research and development and technology transfer.

He advises on the application of competition law to a wide range of agreements, including distribution, agency, franchising, supply, IP licensing, R&D and joint selling agreements. He also advises on pricing and marketing strategies, including online marketing and resale price maintenance. Where appropriate, he can assist with the drafting of these agreements and their termination.

State aid and subsidy control

Matthew has substantial experience of the EU State aid rules, including in relation to applications for EU structural funding under the ERDF and European Social Fund and national programmes such as the Regional Growth Fund. His clients include public authorities, state-owned companies and private sector clients (including companies and charities), whether recipients of aid, their investors or financiers or their competitors. His experience includes advising on public grants and subsidies, public funding for infrastructure projects, public investment (including repayable launch investment), debt relief and forgiveness, and public support for the rescue and restructuring of companies in financial difficulty.

His expertise covers all stages of State aid matters, including: advising on whether a measure constitutes aid and, if so, whether a block exemption applies; advising on structuring measures so as to avoid the requirement to make a notification to the European Commission (“EC”); where notification is required, drafting notification to the EC; drafting complaints to the EC in respect of non-notified aid; advising on EC investigations, whether following notification or a complaint; negotiating commitments with the EC in order to obtain approval; and appeals to the EU General Court and Court of Justice.

EU Structural Funds

Matthew advises local authorities, businesses and others on the State aid and procurement aspects of funding provided by the European Regional Development Fund, European Social Fund and other EU structural funds. This includes advising on ensuring that funding is compatible with the State aid rules and that beneficiaries of funding comply with their procurement obligations. He also advises beneficiaries in connection with Ministry of Housing, Communities and Local Government investigations into suspected procurement irregularities which might lead to the claw-back of some or even all funding received.

This covers a range of matters, including; compliance with licence conditions; modification of licences following a merger, acquisition or financial restructuring; price controls and their periodic review; access to regulated infrastructure, including access charges; and regulatory investigations.
