Crim. Jurisdiction
A court retains jurisdiction over deft when deft is charged as minor but attains majority during the pendency of the proceedings.
No abuse of discretion in court's decision to try deft as an adult for crime committed five years ago, given continued misbehavior and lack of state rehabilitation facilities.
USA v. Leslie J. Woods
Since 2011. An occasional commonplacing of the U.S. Circuit Courts of Appeal.
Neither an authoritative statement of the law nor legal advice. Quick work.
