A lawyer representing two imprisoned teachers, a Canadian and an Indonesian, says they will appeal a Supreme Court ruling that overturned their earlier acquittals on charges of sexually abusing three children at a prestigious international school.

Neil Bantleman and Ferdinant Tjiong were sentenced to 10 years in prison last April by the South Jakarta District Court, but were acquitted by the High Court in August. On Wednesday, the Supreme Court overturned the acquittals and ordered them to serve 11-year prison terms.

Their lawyer, Patra M. Zein, said Friday they will request a judicial review after they finish studying the verdict and gather new evidence.

Canada and the United States both expressed shock at the Supreme Court decision.
