The Clerk of the Dáil has received the final report of the Smithwick Tribunal.
It is expected the report will be released in the near future.
The tribunal was set up in 2005 to examine if a member of the gardaí had passed information to the IRA that allowed them time to set up an ambush in which two RUC officers were murdered.
Superintendent Harry Breen and Superintendent Bob Buchanan were shot dead just minutes after leaving a meeting in Dundalk Garda Station in March 1989.
After several years conducting private investigations, public hearings in front of Judge Peter Smithwick began in June 2011.
They concluded earlier this year.
During those months, evidence was given by current and retired gardaí, as well as RUC and PSNI officers.
British Army undercover agents, politicians and members of the public who witnessed the killings also gave evidence.
The tribunal report is expected to be viewed by the office of the Director of Public Prosecutions before it is published.
