The historic Air-India trial came to an end in Vancouver on Friday with Judge Ian Josephon announcing that he will deliver his verdict on March 16 next year.
At $130 million, it was the costliest trial case in Canadian legal history. And with 331 deaths, it was the deadliest disaster in the aviation history.
The court will sift through hundreds of testimony and piles of documents before deciding the fate of the two accused -- businessman Ripduman Singh Malik and preacher Ajaib Singh Bagri.
The duo faces charges of murder, attempted murder and conspiracy in the worst case in aviation history in which two blasts killed 331people on June 23, 1985.
The accused are said to have loaded two suitcases carrying bombs on to the planes at the Vancouver International Airport.
The first bomb went off at Narita airport in Tokyo, killing two baggage handlers who were shifting the luggage on to an Air India flight.
About 55 minutes later, the other bomb went off on the Air India Flight 182 off the Irish coast, killing all 329 passengers.
Talwinder Singh Parmar, alleged to be the mastermind in the plot, was killed in an encounter with Punjab Police in 1992. And Inderjit Singh Reyat, who pleaded guilty to manslaughter, is currently serving five-year jail term.
In the trial against Malik and Bagri, the prosecution lawyer argued that the two were part of a militant group which aimed to avenge attack on the Golden Temple by the Indian Army in June 1984 to flush out Sikh extremists.
