In September 2013, Lord Justice Christopher Clarke …found the claims to be  “an elaborate and artificial construct…replete with defects, illogicalities and inherent improbabilities” resulting in the case being “essentially speculative and opportunistic”

…..in November 2016, …Lord Justice Tomlinson, hearing the appeal, also strongly criticised the conduct of both the funders and Clifford Chance. He said it was “surprising and depressing” to report the “aggressive and unacceptable correspondence from Clifford Chance, the product of the misplaced zeal of the partner responsible, Mr Alex Panayides”, while highlighting that firm had an “acute conflict of interest which worsened as their own investment in the case increased over time”.
