In an admiralty action arising from plaintiff-employer's suit against defendant, an injured fisherman employed on one of its boats, to dispute the duration and amount of 'maintenance and cure' payments to which defendant is entitled under admiralty law, the district court's judgment is: 1) affirmed as to plaintiff's ability of offset overpayment against any damages that defendant may win at trial; and 2) reversed as to the district court's determination of a date on which plaintiff's obligations terminated because insufficient notice and opportunity to contest otherwise was given to defendant.
