Phrase, idiom, or expression for putting forward one's own requirement by saying that it comes from someone else

Question

Context

My boss one day called me into his office and said that I now had to include tasks 3, 5, and 6 to complete the entire assignment. Traditionally, the usual sequence of task was from 1 through 10, but management had stopped 3, 5 and 6 many years ago.

The boss said it is management that has instructed this, but he does not know that I am in the panel to make amendments to the procedure if anything is pushed for a change. Thus this is his own quirkiness that he wants to impose this additional requirement in the name of management (without their approval). So I want to know what is the phrase, idiom, or expression appropriate for putting his own requirement by saying that it is management's instruction.

I feel this would count as duplicate, but I tried searching for this and really couldn't ascertain whether alternative word like name dropping completes my requirement particularly (it could but I have no way to ascertain). So I will leave it to the expertise of others.

Answer 1

An expression for disclaiming responsibility is "passing the buck". Collins Cobuild defines this as:

If you pass the buck, you refuse to accept responsibility for something, and say that someone else is responsible.

Dictionary.com has this:

To shift blame from oneself to another person: “Passing the buck is a way of life in large bureaucracies.” (See the buck stops here.)
