In an article written three years ago, this author introduced the subject with the observation that, of the several grounds for a new trial in Washington, one in particular had created considerable difficulty for the supreme court, trial judges, and counsel. This was the rule permitting a new trial when "substantial justice has not been done," and followed by the provision that, "In all cases wherein the trial court grants a motion for a new trial, it shall, in the order granting the motion, give definite reasons of law and facts for so doing."
