If Wisconsin's new domestic partner registry law is overturned, Wisconsin could be faced with quite the legal question.
Julaine Appling is with Wisconsin Family Action, which has filed a legal challenge against the registry with the State Supreme Court. The suit claims a 2006 Constitutional amendment makes the registry invalid.
If the lawsuit succeeds, Appling says it could be similar to a dilemma that California experienced last year. Voters in California outlawed gay marriage in November of last year, but courts let existing same-sex arrangements stand.
Same-sex couples in Wisconsin have been signing up for this state's domestic partner registry since Monday, and legal battles are expected to play out in the future.
