1) I have been invited to review the revision of a paper that I recommended for rejection. I cannot see the updated paper before accepting or declining this second reviewing invitation. Would it be ethical to review it a second time if I advised it to be rejected and the editor overrode my recommendation?
2) Time has elapsed, and now I am almost sure of knowing at least one of the potential authors of this paper (Double-blinded review). It turns out that I might have a conflict of interest with this person. So my first ethical instinct is to decline the revision of this paper because of this alone.
Any comments much appreciated, thank you.
