change her mind and refuse to sell it, Supreme Court heard yesterday.

Lawyer Mr. Robin McMillan argued no enforceable contract existed that said he had to sell the Riddell's Bay island and its 15-room mansion.

Trucking tycoon Michael DeGroote has taken Mrs. MacMillan to court to try to enforce an agreement she signed to sell him the property.

She later backed out of the $8.5 million deal, and says she wants to set up a counselling retreat on the island.

Mr. McMillan, summing up Mrs. MacMillan's case, said even if there were an enforceable contract, his client was entitled to cancel it.

Law firm Appleby, Spurling & Kempe, acting for Mrs. MacMillan, had also acted for Mr. DeGroote and "were not on her side at all''.

She had therefore been at a disadvantage and did not get the best professional advice necessary.

There was also a conflict over the role of realtors Cooper Associates, who were co-brokers of the deal with the Bank of Butterfield's real estate firm Betco.

Mr. DeGroote has told the court Coopers acted for him. But Mr. McMillan said the firm was getting its commission from Mrs. MacMillan, and would receive more commission as the price of the island went up.

Discussing legal precedents with Puisne Judge the Hon. Mr. Justice Ground, Mr.

McMillan acknowledged the case was "very peculiar and unusual''.
