Linklaters is facing a £4.6m negligence claim from the All England Lawn Tennis Ground – the club behind the annual Wimbledon tennis tournament.
It is seeking damages for advice the firm provided on the settlement of a claim against architect and design practice Building Design Partnership (BDP) and construction company FB Ellmer.
The claim, which was issued by CMS Cameron McKenna associate Aidan Steensma, centres on a previous dispute between the club and the two construction companies, which were commissioned to design and build the Millennium Building within the grounds. The building, which was completed in 2000, houses facilities for players and members.
The club claimed that the building leaked because of the materials used to construct it and sued for compensation to pay for repair work.
Linklaters advised on the settlement of that claim, but the club now says the firm drafted the settlement in such a way that it could not pursue further damages should the repairs cost more than anticipated.
Last month Linklaters won a court case brought by Baltic telecoms company Levicom, which had sued the firm over advice provided during a dispute with telecoms company Tele2.
Had the case gone against Linklaters it would have had to pay $55m (£37m) to Levicom. Mr Justice Andrew Smith ordered the firm to pay just £5 in nominal damages and Levicom to pay £1.25m in costs to Linklaters, the equivalent of half the £2.5m the firm had built up in legal fees.
