MOSCOW, June 7 - RAPSI. A St. Petersburg court has upheld a magistrates' court decision to fine founder of a LGBT rights organization Nikolai Alexeyev $150 for propagating homosexual relations among minors.

Alekseyev was detained on April 12 for carrying a poster quoting famous Soviet actress Faina Ranevskaya, "Homosexuality is not a perversion, field hockey and ice ballet are."

The magistrates' court found his actions to contain elements of gay relations propaganda among under-18s and, for the first time in St. Petersburg, fined him in accordance with a new law enacted on March 30.

"The lower court's judgment has been upheld and shall enter into force today," Alexeyev told RIA Novosti, adding that he intends to use this decision to challenge the law in the Constitutional Court and the European Court of Human Rights.
