Sounds to me like your opportunity for comment on the bill was simply a ceremonial formality, and those assembled already had their minds made up (or their votes bought and paid for) ... and your insightful, useful, and knowledgeable comments were a mere obstacle to their already-decided vote.
It's hilarious that, at the 11th hour, one politician gets scared that this thing might effect lawyers. Oh, the humanity! Only to be reassured, no, lawyers won't be affected, because, and I quote "um ... common sense ... um ... don't worry, no".
Of course lawyers wouldn't be affected by politicians' screwups. Professional courtesy and all.
