LONDON, Sept 30 (Reuters) - One of the main clearing houses for Argentine debt payments said on Tuesday it always obeyed court rulings, after Argentina deposited a coupon installment with a newly appointed trustee in defiance of a U.S. court order.

"Clearstream is monitoring the situation closely and always complies with court rulings on this subject," said a spokesman for Clearstream.
