The case is not due to go to trial until April but Beattie and Regan's lawyer, John Eichelbaum, yesterday applied for the court to strike out the claims against his clients.
Eichelbaum said many of the issues in the High Court action had already been heard during a 13-day Employment Court fight in May last year and that there was an overlap between the cases.
A judgment has yet to be released in the Employment Court proceedings, where Eichelbaum said Beattie and Regan had already been cross-examined at length.
"It just can't occur again," he said.
Premier's lawyer, Mihai Pascariu, said his client wanted the matter to proceed and that the High Court case had distinct causes of action from the Employment Court proceedings.
Justice Rebecca Ellis, who was hearing the strikeout application, reserved her decision.
This story has been changed from a previous version, which incorrectly said Gill had stepped down as a director in March 2010. The directors who stood down were Beattie and Regan.
