With Orrick Herrington & Sutcliffe this week pulling the plug on a merger bid with SJ Berwin, the question now is whether the UK firm pushes on with its efforts to secure a US merger.

As best as can be gathered, it was never quite as simple as a two-way discussion with Orrick. As Legal Week reported in February, the City law firm had identified a small list of US firms – including Orrick – with which it intended to explore whether to pursue a transatlantic deal. Two other firms definitely on that list were Boston’s Goodwin Procter and New York’s Proskauer Rose.
