owner for tax redemption

A law authorizing the redemption of lands so sold, ought to receive a liberal and benign construction in favor of those whose estates will be otherwise divested... we are abundantly satisfied that it comports with the words and spirit of the law, to consider any person who has any interest in lands sold for taxes, as the owner thereof for the purposes of redemption. Any right, which in law or equity amounts to an ownership in the land; any right of entry upon it, to its possession, or enjoyment, or any part of it, which can be deemed an estate in it, makes the person the owner, so far as it is necessary to give him the right to redeem.
