Reverse cross border mergers could become a popular device for UK companies seeking to maintain and preserve “passporting” or other EU rights.

The mechanism of a reverse cross-border merger (in this context whereby a UK parent company merges with their continental European subsidiary) has not historically been permitted under English law. However the provisions of an EU directive implemented in the UK in 2007 changed that position giving UK company groups that option.

A party's right to terminate a contract in the event that the other party becomes insolvent is one of the most commonly seen termination rights in outsourcing and technology agreements. However, the effectiveness of such provisions in the future could change in agreements governing the provision of IT services, as the new Enterprise and Regulatory Reform Act 2013 gives the Government the power to extend the law that currently protects supplies of gas, water, electricity and communication services during an organisation's insolvency to the supply of IT services.

On 13th August 2013, the US Department of Justice (DOJ) and attorneys general from six US states and the District of Columbia filed suit in the US District Court for the District of Columbia to block the merger between US Airways and American Airlines. Days before, a group of American Airlines customers filed a claim that the merger would violate Section 7 of the Clayton Act.
