The Windsor, Ont. man who sued for six digits in compensation after finding a fly in his bottled water, has lost his case.

The Supreme Court of Canada voted unanimously on Thursday to dismiss Martin Mustapha's appeal, and ruled he must pay the costs for the water company he took to court.

Mustapha and his wife found the dead fly, then later found half of another fly, in a large water bottle delivered to their home.

The hairdresser claimed to have suffered serious psychiatric symptoms after the incident, including sleeplessness and a major depressive order. He also claimed his sex life and his business were affected and he developed a phobia of flies.

Mustapha successfully sued the bottled-water company -- Culligan of Canada Ltd. -- in 2005 and was awarded $341,000.

"Although his reaction was 'objectively bizarre', his particular circumstances, along with Culligan's knowledge that the nature of its product indicated a concern for purity and cleanliness, made psychiatric injury from the incident foreseeable for Mr. Mustapha," said a Supreme Court summary of the case.

However, Culligan appealed and the decision was overturned.

The appeal court ruled that the trial judge "erred in failing to incorporate an objective component when determining whether Culligan owed a duty to Mr. Mustapha" according to the document.

The court also said the judge "erred in asking whether psychological harm to Mr. Mustapha was possible rather than probable," and ordered Mustapha to pay Culligan's legal bills.

Mustapha then took the case to the Supreme Court, which quashed his case Thursday.

According to an earlier SCC summary of the case, the test for existence of duty of care is whether it is foreseeable that a person of "normal fortitude or sensibility" would be likely to suffer psychiatric harm from such an incident. If so, the defendant can be held accountable for the plaintiff's psychiatric harm.
