Last week's oral arguments in two landmark cases involving same-sex marriage will likely not be followed by opinions until late June. In the interim, there will be a great deal of speculation about what various rulings might mean. With respect to the legal challenge to Section 3 of the Defense of Marriage Act, speculation about the outcome will be less common because most legal observers (including me) expect a comfortable majority of the Court to strike it down. With respect to the challenge to California's Proposition 8, however, the outcome is less certain. Each outcome will lead to markedly different developments for gay and lesbian rights. For this reason it's worth teasing out the implications of the possible rulings in the challenge to Prop 8.
