Legal Question in Criminal Law in Minnesota

Re: I was told that it is illegal to sell a used toilet. Is this true?

If there is a criminal statute prohibiting selling a used flush toilet fixture in Minnesota, I am unaware of it. Sometimes when a person says something is "illegal" they may be referring to a regulatory rule or local ordinance. I do know that in Minneapolis there are used plumbing fixture shops that sell used toilet fixtures. You might ask them.
