Based on my own judicial experience that goes back to 1961, I suggest that 90 percent of the cases appearing before a court of general trial jurisdiction or general appellate jurisdiction fall within two categories: where the law and its application alike are certain, or where the law is certain and the only question concerns its application to the facts before it.
