By Reuters Staff (This January 21 story corrects to remove erroneous reference to next year in third paragraph) TEGUCIGALPA (Reuters) - Members of the Honduran Congress voted on Thursday to amend the constitution making it much harder to reverse existing hard-line bans on abortion and same-sex marriage, as lawmakers double down on socially conservative priorities. Lawmakers voted to require a three-quarters super-majority to change a constitutional article that gives a fetus the same legal status of a person, and another that states that civil marriage in the Central American nation can only be between a man and a woman. With 88 legislators in favor, 28 opposed and seven abstentions, the proposal will still need a second vote in the unicameral legislature before it is enacted.
