The Minnesota Supreme Court is hiking registration fees for lawyers to raise more money for public defenders and legal aid for the poor.The $100 increase is meant to expire after two years, and raises the annual registration fee for most lawyers to $317.In Thursday's order, chief Justice Eric Magnuson writes that the Supreme Court is raising the fees reluctantly.He says civil legal services and the public defender system are ``dramatically underfunded,'' and the court system is suffering as a result.
