Commerzbank, the German lender, will today begin its legal appeal against a London court ruling that ordered it to pay 104 ex-Dresdner Kleinwort bankers €52m in unpaid bonuses. The bankers said they had been promised a €400m guaranteed bonus pool by former Dresdner Kleinwort chief executive Stefan Jentzsch in August 2008. Commerzbank acquired Dresdner Bank the following year, and scaled back the bonuses paid out in early 2009. Commerzbank said at the time that the payout was not justified after Dresdner Kleinwort made significant losses. The appeal will be heard for three days in the Court of Appeal by three judges; Lord Justice Elias, Lord Justice Kay and Lord Justice Beatson. The outcome of the appeal will come in between six to eight weeks time.
