   Still, there won't be any quick changes.  Under Mexican law,
two more cases from Oaxaca must be decided in the same way
before a precedent is established allowing gay marriage—and only
in that state. For each of Mexico's 30 other states, five
separate cases would have to be decided that way to establish
precedent for gay marriage.   Experts say the Oaxaca ruling puts
gay couples in the state a step closer to being able to get
legally married.  "They are rulings that will favor the
recognition and nondiscriminatory access to marriage," said
Miguel Rabago Dorbecker, a law professor at Iberoamerican
University in Mexico City.  The decision issued Wednesday was
well received by the Mexican gay and lesbian community that
still hopes to achieve the same rights as heterosexual couples.
"This makes it possible for the new generations of gays to see
some hope that Mexico will recognize their rights, and that they
can one day live their sexuality openly," said Jaime Lopez,
president of a gay civil association.  Lop
