Star-Tribune indicates that the "Reps. Bob Nicholas, R-Cheyenne, and Frank Peasley, R-Douglas, who cast the deciding votes against the bill, opposed the proposal not on ideological grounds, but rather because they worried the wording of the bill -- which almost exactly mirrored the rights and responsibilities Wyoming law lists for marriage -– could lead to legal pitfalls in the future.
For example, Peasley pointed to a part of the bill stating that in a Wyoming civil union, like a marriage, the man in the partnership would be considered the father if the woman gets pregnant.
"What if it's two women that get into a civil union and one of them's pregnant?" Peasley asked. "How do we work that one?"
State Rep. Cathy Connolly, the Laramie Democrat who sponsored the bill, answered that "those were sticky wicket questions that might end up in court."
The problem it is that during this meeting instead of speaking about the nuances of the law, they were more focused on the merits of gay relationships and same-sex marriage rights.
