Prosecutors in the Air India case are getting more time to decide whether to appeal the acquittals of the two men who were charged in Canada's worst mass murder.

Justice Risa Levine of the B.C. Court of Appeal gave the Crown until May 13 to make the decision.

In granting the 30-day extension on Wednesday, Justice Levine said the complexity of the case and the amount of material involved justified a delay.

Ripudaman Singh Malik and Ajaib Singh Bagri were found not guilty on March 16 of murder and conspiracy charges in the two-decade-old bombing.

Bombings kill 331

Air India Flight 182 blew up on June 23, 1985, off the Irish coast en route from Toronto to Mumbai. All 329 people on board died.

Less than an hour later, two baggage handlers at Tokyo's Narita Airport died when a suitcase exploded as it was being transferred from a flight that originated in Vancouver.

A third man, Inderjit Singh Reyat, pleaded guilty to manslaughter in the case and is now serving a five-year sentence.

On Tuesday, the House of Commons voted in favour of a non-binding motion for a public inquiry into the Air India case.

Public Safety Minister Anne McLellan says she will appoint an adviser to assess the situation before deciding whether she will order an inquiry.
