“One of the cleverest people you could hope to meet. He gets down into the tiniest details of a case and has a fantastic strategic overview.”
David has a commercial and chancery practice with a particular focus on disputes involving complex financial or quantum issues. He is often involved in large commercial matters, where he brings a rigorous and imaginative approach to finding the arguments most likely to prevail. Major cases in which David has been involved includes the litigation arising out of the collapse of Lehman Brothers, the test case on the fairness of bank charges and the group litigation relating to the RBS’s £12bn rights issue in 2008. David also deals effectively with discrete arguments of law or construction, as in his representation of the successful appellant in Brightsea UK Ltd Drachs Investments No.3 Ltd [2012] EWCA Civ 516 (dealing with the construction of a Tax Deed). David’s trial experience includes Singer v Beckett [2007] 2 BCLC 287, a 72 day wrongful trading trial at the end of which Park J described David as “remarkably gifted in relation to difficult financial and quantum issues” and commented “I can imagine how [the key witness on quantum] felt as Mr Blayney’s (totally charming and courteous) cross-examination progressed, demolishing large tracts of his evidence…”
