The thought was whether leaving a pos (no matter if it has pos or neg comment) would negate opening a case or strike being removed as the transaction must have been successful if pos feedback left.

But it makes more sense those 2 systems don't interact and left in control of ebay.

But as DG pointed out possibly if a buyer appeals and has a pos on the trans, maybe it is easier to have it removed and I think that is where the misunderstanding has occurred.

Thank you all, querie sufficiently answered. 🙂
