The row over shares in the Coopers brewery company held by a family member who wishes to sell a 9% stake to Lion Nathan could soon go to trial, a Supreme Court judge has said.

Mary Phyllis Henderson is attempting to gain control over 114,000 Coopers shares which were part of a family will some 15 years ago. Henderson's lawyer, Lindy Powell, said Henderson would earn A$30m if she sold the 9% stake to Lion Nathan. But the Public Trustee and three members of the Coopers family are attempting to prevent this.

In the Supreme Court, Justice John Perry adjourned the hearing until later this week but told all parties that he was likely to submit the case for trial.
