Opinion of the Court by
Reversing.
This is an action under tbe Declaratory Judgment Act, (chapter 83, 1922 Acts). Its purpose is to obtain a declaration whether a judgment in a former action adjudging certain parties thereto to be tbe only heirs of Samuel Lyons deceased would be binding and protect tbe administrator and bis bondsmen if other heirs should hereafter appear and make claim against tbe administrator for a part of the estate.
It is set out in tbe petition and not denied that in addition to all of tbe known heirs (twenty in' number) bis “unknown heirs” were made parties defendant to that action and proceeded against by warning order as authorized by section 691 of tbe Civil Code of Practice, but only tbe administrator and two of tbe known heirs are parties hereto.
*568Section 6 of the act provides that the court may refuse to exercise the power to declare rights in any case where a decision would not terminate the uncertainty or controversy which gave rise to the action; while section 9 provides that when declaratory relief is sought all persons who have or claim any interest which will be affected by the declaration shall be made parties.
Since decedent’s unknown heirs are not made parties hereto as provided by section 691 of the 'Code, it is clear that any decision in this case could not possibly be binding upon them, if any there be, and the lower court, therefore, should have declined to declare the rights of those who were parties to this action and dismissed same without prejudice. Axton v. Goodman, 205 Ky. 382, 265 S. W. 806; Ezzell v. Exall, 207 Ky. 616, 269 S. W. 752; Coke, et al. v. Shanks, Auditor of Public Accounts, et al., 209 Ky. 723, 273 S. W. 552.
Besides, this court in Shearer, et al. v. Backer, et al., 207 Ky. 455, 269 S. W. 543, held that, “Questions already adjudicated by a court having jurisdiction of the subject matter and the parties, cannot thereafter be the subject between such parties and their privies of ‘an actual controversy’ within the meaning of those terms in sections one and six of the Declaratory Judgment Act.”
Wherefore, the‘judgment is reversed with directions to dismiss the petition without prejudice.
