Gay pride organizers in South Korea won a case filed against them on Tuesday by conservative Christians and members of the police force, overturning a ban on a gay pride parade in Seoul.

Christian groups believe that the gay pride parade heavily promotes the doing of "evil" behavior, while police made mention of public safety concerns and disruption of traffic that made them make the ban that was imposed last month.

However, the Seoul Administrative Court ruled in favor of the parade. The South Korean rights activists celebrated the court's decision on Wednesday, according to Agence France-Presse.

"Assemblies can be prohibited only when they directly threaten public order," said the court in an official statement.

The court also emphasized on the fact that the organizers have already prepared months in advance for the yearly parade and that if the event had been canceled, the organizers would have to endure great damage.

With the police ban rendered invalid, the gay pride parade will go as scheduled, taking place on June 28 in the centre of Seoul. The event will also be the culmination of the festival that started on June 9.

The gay pride parade organizers revealed that more than 20,000 people, including lesbians, gays, bisexuals and transgenders, are expected to participate in the celebration, AsiaOne reported.
