The legal action being brought by the French drinks and luxury goods group, LVMH, against Morgan Stanley, regarding accusations of bias in the bank’s research faces a delay, with the US investment bank asking the court to determine if LVMH has disclosed all its evidence.

LVMH has branded the request by Morgan Stanley as a delaying tactic.

The judge has set a date of April 1 for a hearing to determine whether a procedural error was committed and whether LVMH had retained evidence relating to its claims that Morgan Stanley’s research was biased.

The judge will rule after that hearing and set a date for the US$100m lawsuit to resume in the Paris commercial court.
