The prosecution lawyers have wrapped up their arguments in the 20-year-old Kanishka bombing case.
The Air-India's Kanishka flight was blown up off the Irish coast on June 23, 1985, when it was on its way from Toronto to India via London, killing all 329 passengers onboard.
A second bomb exploded at Tokyo's Narita Airport, killing two baggage handlers.
The main accused in the case, Ajaib Singh Bagri, and co-accused Ripudaman Singh Malik will get one last chance to rebut evidence against them in what is considered the most expensive trial in Canadian history.
Prosecutor Richard Cairns on Friday said the prosecution has proven its case against Bagri. "The person who committed this crime is a fanatic without any empathy for his fellow men," the prosecution argued, a media report said.
The prosecution charged Bagri with wanting to "destroy the Indian government and Air-India." Bagri felt the Indian government was acting against the interests of the Sikhs.
The defence team for Bagri is expected to argue that his rights were violated when the Crown prosecutors allegedly
failed to disclose information in a timely way.
