Oct 7 (Reuters) - An appeals court on Friday temporarily blocked Arizona from enforcing a 1901 ban on nearly all abortions in the state, overruling a trial court's decision last month to let the ban proceed. The Arizona Court of Appeals granted Planned Parenthood's request for an emergency stay of Pima County Superior Court's ruling on Sept. 23 that lifted an injunction on the ban. The appeals court said the abortion-rights advocacy group "demonstrated a substantial likelihood of success" in its challenge of that decision. Planned Parenthood said in a statement the decision by the appeals court "brings temporary respite to Arizonans" and would allow the group to resume abortion care services while the legal proceedings continue. Democrats are increasingly hopeful the Supreme Court decision will boost voter support in November's midterm elections, with the party's control of both the House of Representatives and the Senate at stake.
