Stewarts Law, Mishcon de Reya and Quinn Emanuel Urquhart & Sullivan have settled their clients’ claims against the Royal Bank of Scotland (RBS) in the mammoth £4bn rights issue litigation.

The three firms, which represent a raft of major investors, will attend a private court hearing this week to hash out the admin related to the settlement.

RBS is understood to have agreed to pay £800m to the shareholders, representing approximately 41p for every £1 invested.

Stewarts partner Clive Zietman penned the letter to the judge regarding the hearing, which is understood to have been submitted today (5 December). Attached to it was a court order signed by the three settling parties.

More than 24,000 corporate and individual investors represented by Signature Litigation and, to a lesser extent Leon Kaye, have not settled and are heading towards trial, which will begin on 6 March 2017.

RBS CEO Ross McEwan said in a statement: “We have been very clear that we wanted to deal with as many of our legacy litigation issues as possible during 2015 and 2016.

“We are pleased to have reached this agreement and hope that it will be accepted by the remaining claimant groups so that this long course of complex and costly litigation can now be concluded.”

The colossal case first launched in 2014 with four claimant groups alleging RBS’s £12bn rights issue in 2008 was defective and contained “material misstatements and omissions”.

Mishcon later came on the record for the Lloyds institutional investors and Investec after the claimants split off from the RBS Shareholders Action Group, represented by Signature.

The Signature group, now represented by firm head Graham Huntley, has been through various legal representation, first instructing Bird & Bird then Fladgate and then Signature.

RBS has instructed HSF partners Simon Clarke, Adam Johnson and Kirsten Massey on the case, with the firm previously estimating that its bill until the end of a trial on quantum would exceed £100m.

The bank and HSF were criticised in the High Court last November for their “unfocused”, “unsettling” and “less than compelling” approach to disclosure in the battle with shareholders.

Mr Justice Hildyard ruled RBS’s disclosure process “appears not to have been informed by any sufficient early attempt to grasp what would truly be involved”, adding its approach had been “diffuse”.
