Sullivan & Cromwell has emerged as counsel to embattled newspaper baron Conrad Black in his increasingly acrimonious negotiations with Hollinger International.
Litigation partner John Warden is acting for Lord Black who is currently engaged in talks with his newspaper empire about the repayment of compensation that was paid out to Black and a number of executives connected to Hollinger International.
Lord Black had promised to repay $7.2m (£4m) in compensation, part of $32m (£18m) worth of non-compete fees related to the sale of titles sold in 1999 and 2000 that had been received by the peer and a group of executives.
A sum of $700,000 (£386,000) should have been paid by December 31 by Lord Black to Hollinger International though the newspaper group has granted its former chief executive a two week deadline.
However Lord Black is now asserting evidence has emerged that the payments were authorised, a claim that the board of Hollinger International is disputing.
Acting for Hollinger International is Herbert Smith with US advice provided by Paul Weiss Rifkind Wharton & Garrison.
