The committee had faced criticism from two members
The Oireachtas Committee on the 8th Amendment is set to hold its final public meeting on Wednesday.
The group is also to prepare a draft report as it completes its examination of the recommendations of the Citizens' Assembly.
Committee chair Senator Catherine Noone said: "At our meeting, the committee will complete its examination of the report and recommendations of the Citizens' Assembly through voting process and we will then prepare our draft report in accordance with the committee's terms of reference."
The committee had faced criticism from two members.
TD Mattie McGrath and Senator Rónán Mullen alleged its work has been fixed to deliver a particular outcome.
Speaking in October, chair Senator Catherine Noone said that was not the case.
"Allegations of bias really are unfounded, as far as I'm concerned as chair.
"There was a clear methodology that we would look to the Citizens' Assembly for certain witnesses - and many of those appear in the work programme.
"And the other witnesses were suggested by members of the committee".
The committee has voted that the 8th amendment should not be retained in full in the Constitution.
It has been tasked with deciding between six possible options to be put to the people by referendum.
These range from a simple repeal of the 8th, to repeal and replacing it with a new law.
While the Taoiseach Leo Varakar has confirmed a referendum on the 8th amendment will take place in May or June next year.
