For a window into how legislation is made, few moments were more educational than a sparsely attended meeting Tuesday afternoon in a cavernous, mostly empty room on the University of New Mexico campus. On the surface, the meeting was congenial as two state lawmakers, legislative staff, attorneys and representatives of civic organizations hammered out the beginnings of draft legislation that would fill out the details of the state’s first independent ethics commission if voters give the go ahead in November. But beneath the amicable discussions there was a rematch of sorts, perhaps noticeable only to those aware of the contentious history surrounding the idea of an independent ethics commission. For almost 15 years, lawmakers offended by the notion that they needed anyone to watch over them squared off against other legislators who touted independent oversight as a way to restore public trust in government. Legislative opposition knew no political party, with both Democrats and Republicans chafing at the idea of an independent oversight body.
