Relative Clauses at the end of the sentence

Hi teachers,
I know the following are relative clauses inside the main clause.
Robert, who works at Mr. Landon's bookstore, is often late at work.
b) The rules, which are Mr. Landon's, require a suit and a tie.

My question is, are the following relative clauses at the end of the main clause based on the ones above? If not could you correct them please?
I know Robert, who works at Mr. Landon's bookstore.
Robert doesn't like the rules, which are Mr. Landon's. Or Robert doesn't like the rules, which require a suit and a tie.

Thanks in advance.
