It's the Senate's Constitutional responsibility to advise and consent the President's SCOTUS nominations. What is the procedure when they abdicate that responsibility? Remember, the Senate didn't tell Obama "no, we don't like your nominee." They, meaning McConnell, refused to hold any hearings on at all.
So maybe he didn't violate the law, but he certainly didn't uphold his Constitutional responsibilities, which I believe is part of the Oath of Office he took.
