Timeline of the Air India Flight 182 affair

The bombings of Air India Flight 182 and the Narita Airport launched several investigations, inquiries and trials. The trial of Malik and Bagri is known as the Air India Trial; events relating to the incident are listed below in chronological order.
 * July 1985 – Canadian Prime Minister Brian Mulroney calls Indian Prime Minister Rajiv Gandhi to offer his condolences, but does not call the victims' families to do the same. This causes an uproar among Indo-Canadians who feel that although this is the deadliest terrorist act to date, it is not taken seriously because the victims although mostly Canadian were not Caucasian.
 * 8 November 1985 – The RCMP charge Talwinder Singh Parmar and Inderjit Singh Reyat with weapons, explosives and conspiracy offenses after a raid on their homes. Reyat is convicted of the weapons offence and receives a fine of $2,000. Because of a lack of evidence, the charges against Parmar are dropped and no link to Air India is established.
 * 22 January 1986 – The Canadian Aviation Safety Board determines that a bomb was responsible for bringing down Air India 182.
 * 4 February 1986 – The Indian Government's Kirpal Commission of Inquiry reaches the same conclusion as the Canadian Aviation Safety Board.
 * February 1988 – Inderjit Singh Reyat is arrested by West Midlands Police in Coventry, UK.
 * 8 December 1989 – Following a lengthy court battle the British government agrees to extradite Reyat, who is a dual British-Canadian national, to Canada.
 * 10 May 1991 – Inderjit Singh Reyat receives a ten-year sentence after being convicted of two counts of manslaughter and four explosives charges relating to the Narita Airport bombing.
 * 9 to 15 October 1992 – Talwinder Singh Parmar interrogated by Punjab Police; apparently names Lakhbir Singh Rode as mastermind, and confesses to supplying the dynamite for the operation. The confession is destroyed, since Lakhbir is said to have been an Indian agent.

 * 27 October 2000 – Ripudaman Singh Malik and Ajaib Singh Bagri are arrested by the RCMP. They are charged with 329 counts of first-degree murder in the deaths of the people on board Air India Flight 182, conspiracy to commit murder, the attempted murder of passengers and crew on the Canadian Pacific flight at New Tokyo International Airport , and two counts of murder of the baggage handlers at New Tokyo International Airport.

"I began by describing the horrific nature of these cruel acts of terrorism, acts which cry out for justice. Justice is not achieved, however, if persons are convicted on anything less than the requisite standard of proof beyond a reasonable doubt. Despite what appear to have been the best and most earnest of efforts by the police and the Crown, the evidence has fallen markedly short of that standard."
 * 7 May 2005 Gurmant Grewal, M.P. tables a Motion in the House of Commons for the Air India Bombing Investigation. Gurmant Grewal on Supply | openparliament.ca
 * 26 July 2007 The investigative magazine, Tehelka, releases reports that a retired police officer has maintained records of Parmar's confession identifying the mastermind as Lakhbir Singh Rode. Most of the confession is already known to RCMP, and the new aspects appear dubious.
