The Superannuation Bill passed its consideration stage, on 22 October 2012.
The Northern Ireland Civil Service (NICS) pension scheme was a statutory pension provision that was established by the Superannuation (Northern Ireland) Order 1972.
If the Superannuation Bill becomes law, the 1972 Order would be amended to remove the need for trade union consent.
Finance committee chairperson Daithi McKay brought forward one amendment asking for the civil service compensation scheme to be subject to negative resolution.
Under this procedure the new regulations will become law unless they are rejected by a resolution within 40 days.
Judith Cochrane of the Alliance Party said she was supportive of maintaining parity with the Westminster government but also said there was a "need to express caution".
Finance Minister Sammy Wilson said he had accepted the proposed amendment and was content for other members to support it.
