This is one part of the Code which I remember well (from my 1st grade “Contractor’s Liability” class)
“If a builder build a house for a man and do not make its construction firm, and the house which he has built collapse and cause the death of the owner of the house, that builder shall be put to death”
Put to death for shoddy workmanship that causes a death? That would sure have an adverse effect on many union workers.
