The British Broadcasting Corp. has retained U.K. firm Pinsent Masons to help handle a settlement in a dispute between the BBC, The Guardian newspaper and leading offshore firm Appleby over the leak of confidential materials last year.

The so-called Paradise Papers hack had led Appleby to hire Osborne Clarke, another leading British firm, in an effort to contain the fallout from that breach. Appleby took legal action against The Guardian and BBC, citing a breach of confidence by both news outlets following the hack in May 2016, although by late day Friday a settlement was announced noting that “all parties had “resolved their differences.”
