When the verdict on Ripudaman Singh Malik, 57, and Ajaib Singh Bagri, 55, is passed, it will bring to a close one of the most exhaustive and expensive trials in Canadian history.

The two accused are charged with planting bombs aboard an Air India plane that exploded on June 23, 1985, on its way from Toronto to India via London [Images]. The mid-air explosion killed 329 people.

Just before explosion, a bomb exploded at Tokyo's Narita Airport, killing two baggage handlers.

British Columbia Supreme Court Justice Ian Josephson will deliver the judgment.

Over 100 witnesses have been examined since the trial began in April 2003. With a specially built courtroom, the trial cost more than $ 100 million.
