JACKSON
v.
The STATE.
No. S08A0365.
Supreme Court of Georgia.
April 21, 2008.
Alexander Jackson, Jesup, pro se.
Spencer Lawton, Jr., Dist. Atty., George R. Asinc, Asst. Dist. Atty., for appellee.
SEARS, Chief Justice.
The appellant, Alexander Jackson, appeals from the habeas court's order ruling against his claim that he received ineffective assistance of counsel when he pled guilty to two drug possession offenses. We conclude that the habeas court's judgment must be affirmed.
The habeas hearing transcript and Jackson's affidavit show that he testified that, when he pled guilty, he was not informed of the nature and elements of the drug possession crimes, and that, in fact, his lawyer told him that he could be found guilty merely by being in the same house as the drugs. Jackson also testified that, if he had known that the possession element of the crimes required knowing possession, he would not have pled guilty, but would instead have gone to trial because he did not have knowledge of the drugs that were found. Jackson's trial counsel did not testify at the hearing, as he was not subpoenaed to testify by either Jackson or the State.
To the extent the habeas court ruled against Jackson's claim of ineffective *526 assistance of counsel on the ground that Jackson expressed satisfaction with his attorney's services at the plea hearing, the habeas court erred.[1] Our review of the record, however, demonstrates that the habeas court also ruled against Jackson's claim on the ground that the habeas court did not find that Jackson's testimony regarding his attorney's performance was credible[2] and thus concluded that Jackson failed to overcome the strong presumption that trial counsel's performance was not deficient.[3]
Because we cannot conclude that the habeas court erred by ruling that Jackson failed to carry his burden to prove the ineffectiveness of his trial counsel, we affirm the habeas court's judgment.[4]
Judgment affirmed.
All the Justices concur.
