The state appeals a finding by the habeas trial court that a 1973 guilty plea to murder and armed robbery was not knowing and voluntary. Related issues were raised by Sims in previous habeas petitions filed in 1975 and 1986. The habeas trial court refused to dismiss this petition as successive, held a hearing on the voluntariness issue, and, based on the scanty Boykin [v. Alabama, 395 U. S. 238 (89 SC 1709, 23 LE2d 274) (1969)] record made at the plea of guilty, granted the writ.

Boykin was decided several years before Sims’ guilty plea and the filing of his first habeas petition. He has shown no reason why this claim could not have been raised in the earlier habeas corpus petitions.1 Smith v. Zant, 250 Ga. 645, 647 (301 SE2d 32) (1983). The habeas trial court’s holding that a Boykin claim is non-waivable was error and the motion to dismiss this petition as successive should have been granted. OCGA § 9-14-51.

Judgment reversed.
