It isn't about law. It is about professionalism, and improving your odds of getting the best candidate. It is about business acumen.
If you do what you suggest, you never get to meet better people, never get to have a conversation about how different interviewers see the candidate, never get to think about it, and so much more.
Rushing to hire a guy you love in the moment is a guaranteed way to keep making the same mistakes, to hiring people in your own likeness when what you need is difference, and never knowing why you keep failing.
