The panel of five judges on the East African country's Constitutional Court said the speaker of parliament acted illegally when she went ahead to allow a vote on the measure despite at least three objections over lack of quorum. A Ugandan court is expected to rule Friday on a petition by activists who say the East African country's new anti-gay measure is invalid because it was passed during a parliamentary session that lacked quorum. The law was passed by lawmakers in December and enacted in February by Ugandan President Yoweri Museveni, who said he wanted to deter Western groups from promoting homosexuality among African children.
