The Dáil has passed legislation to allow Ireland host the Rugby World Cup in 2023.
But the bill had to be rushed through before the Summer break after it emerged the former Attorney General changed her mind about it.
Maire Whelan - who is now a judge - originally said legislation would not be needed for the State to guarantee the tournament hosting fee.
However, she then changed her mind and recommended that a bill be forced through.
The bill now goes to the Seanad, but must be signed into law before the end of July in order to support Ireland's tournament bid.
Sinn Féin's Transport, Tourism and Sport spokesperson Imelda Munster welcomed the inclusion of changes that added "an element of financial oversight" to the bill.
Deputy Munster said: “The legislation is vague and poor, and the government has shown no concern that it could lead to problems down the line for the public purse. However, I do feel that the inclusion of Committee oversight has improved it significantly.
“I wish the bid every success. We are hopeful that Ireland’s bid to host the tournament is the successful one, and I commend all involved in the process.”
South Africa and France are also bidding to host the tournament in six years time, with a decision set to be made in November of this year.
