In simple words
Where one instrument is evidence of different rights or different obligations, the court can, in a proper case, cancel it only in part. The rest of the instrument is then allowed to stand. So a court need not cancel the whole document where only some of its rights or obligations should be set aside. The power is exercised only where the case properly calls for it, as the words "in a proper case" show.
