[JURIST] Massachusetts Governor Mitt Romney Thursday announced his support of a drive to put before state voters a proposed constitutional amendment to ban both same-sex marriage [JURIST news archive] and civil unions. Massachusetts is the only US state where same-sex marriages are legal; Vermont, Hawaii, and California have granted same-sex couples limited legal rights. The Massachusetts legislature is already considering an amendment to ban same-sex marriages but allow for civil unions that could appear on the ballot in November 2006 [JURIST report]; the initiative Romney supports would appear in November 2008 at the earliest.
