May the 32nd Dáil allow free votes for TDs

I saw an instance of this back in 1993 when I was campaigning for a ban on hare coursing. The late Deputy Tony Gregory had tabled a Private Members Bill to outlaw the blood sport.
Of the 165 TDs (not counting the Ceann Comhairle) we estimated, on the basis of replies from TDs, 64 would vote for abolition, and 57 would vote against.
