multi-millionaires, could run for years.

Legal experts believe the case, now coming to an end in Supreme Court, could go to the Appeal Court and then to the Privy Council in London, the Commonwealth's highest court.

Last year a dispute between businessman Mr. Brent Kelly and real estate firm Cooper Associates was finally settled by the Privy Council, seven years after the row began.

The dispute centred on a Tucker's Town mansion sold by Mr. Kelly to the son of tycoon-turned-politician Mr. Ross Perot.

The Perot's Island dispute involves grain heiress Mrs. Marion MacMillan and trucking mogul Mr. Michael DeGroote. Coopers are also involved, as is the Bank of Butterfield's real estate firm, Betco.

Mr. DeGroote took Mrs. MacMillan to court after she backed out of a 1990 deal to sell him the island for $8.5 million.

On Thursday Mr. John Riihiluoma, Mr. DeGroote's lawyer, began his summing up of the case.

He said Mrs. MacMillan's accusations against the real estate agents had been long-winded and obscure.

He rejected her "bald allegation'' of breaches of duty by the realtors, allegedly knowingly encouraged by Mr. DeGroote.

Her allegation was more obscure and less tenable now than when stated before the trial, he said.

"There was nothing that any party perceived to be abnormal in Betco acting for Mrs. MacMillan and Cooper Associates acting for Mr. DeGroote.''
