Latham & Watkins and specialist German firm TILP are among more than 900 firms advising on a landmark legal case against Deutsche Telekom, which reached court earlier this month (7 April).

The closely-watched case, which began in 2001 and is the first test case for Germany’s newly-introduced group action rules, sees 17,000 shareholders suing Deutsche Telekom for a reported E80m (£63m).
