ST. JOHN'S, N.L. - The Crown will confirm in court next week whether a Newfoundland man convicted of drowning his twin daughters after a so-called Mr. Big police sting will face a new trial.

Crown prosecutor Frances Knickle says Nelson Hart will appear Tuesday in provincial Supreme Court in Gander, N.L.

She said any plans to pursue a new trial will be confirmed then.

Crown prosecutors and the provincial attorney general's office have been reviewing a ruling Thursday from the Supreme Court of Canada.

It cast doubt on the reliability of Mr. Big stings and said a confession Hart made to undercover police officers posing as gangsters can't be used against him.

Lawyers who appeared for Hart in the past say without the confession there is no evidence he committed any crime.
