Pinsent Masons is advising the BBC as the broadcaster and The Guardian newspaper reach a settlement with offshore law firm Appleby over the 'Paradise Papers' data hack.

The litigation, which was settled on Friday afternoon (4 May), comes after Appleby took legal action against both news outlets, citing breach of confidence following the data hack in May 2016.

In an agreed statement, the parties announced they had "resolved their differences".

The statement continues: "Without compromising their journalistic integrity or ability to continue to do public interest journalism, The Guardian and the BBC have assisted Appleby by explaining which of the company's documents may have been used to underpin their journalism. This will allow Appleby to initiate meaningful discussions with its clients, colleagues and regulators."

The offshore firm had alleged that information leaked to German newspaper Sueddeutsche Zeitung (SZ) and subsequently passed onto The Guardian and BBC was "obtained unlawfully" in circumstances "likely to have amounted to the commission of a criminal offence or cyber-hack".

Appleby said the leak coverered 6.8 million documents dating back to the 1950s, including loan agreements, financial statements, records of approaches from potential clients and records of legal advice, among other information.

The particulars of claim alleged that The Guardian and BBC should have known the information they had access to was confidential and subject to legal privilege, and that the publication of the documents did not meet the public interest test as "there was no ground to suspect that the confidential information disclosed illegal conduct" either by Appleby or its clients.

The offshore firm was seeking the delivery, destruction or deletion of the information, as well as financial damages covering the costs of dealing with "regulatory entities, clients, employees and agents".

In their defence, both the BBC and The Guardian argued that there was a strong public interest in the publication of the information from the leak, while the BBC's defence states that there were grounds for suspecting that the data contained evidence of unlawful activity by Appleby or its clients.

Both the BBC and The Guardian stated that they were unaware of the source that passed the leaked documents to SZ, and argued that they acquired the information lawfully.

A BBC spokesperson said: "We will continue to defend our journalism robustly."

Pinsents technology, media and telecoms disputes partner David Barker acted for the BBC, with Catrin Evans QC of Matrix Chambers and Jonathan Scherbel-Ball of One Brick Court instructed as counsel.

In December, Legal Week revealed that Appleby had turned to Osborne Clarke for advice on the dispute, with litigation partner Ashley Hurst acting for the firm. He is joined by Hugh Tomlinson QC and Lorna Skinner of Matrix Chambers.

The Guardian was represented by its in-house director of editorial legal services Gillian Phillips, with Gavin Millar QC of Matrix Chambers and David Glen of One Brick Court as counsel.

Appleby is one of the world's best-known offshore law firms, with offices in Bermuda, the British Virgin Islands, Cayman Islands, Hong Kong, Mauritius, Seychelles and Shanghai. Its clients include Uber, Apple and Nike, as well as accounting giants KPMG, EY and PwC.

The firm said it had "thoroughly and vigorously" investigated the allegations prompted by the leak and that it was "satisfied that there is no evidence of any wrongdoing, either on the part of ourselves or our clients".

The Paradise Papers revelations came on the back of the earlier 'Panama Papers' leak from offshore firm Mossack Fonseca, which this March announced that it was closing down.

The Panama-based firm said it had suffered "irreparable damage" due to "the reputational deterioration, the media campaign, the financial siege and the irregular actions of some Panamanian authorities" in response to the leaks.

The Guardian declined to comment. Pinsent Masons was contacted for comment.
