Dist. Ct. did not err in denying defendant’s habeas petition that challenged his guilty plea to drug conspiracy charge, as well as his 540-month term of incarceration on grounds that govt. breached agreement to recommend sentence of between 108 and 135-months incarceration, and that his guilty plea was not voluntary. Record did not support defendant’s contention regarding existence of agreement as described by defendant, and defendant otherwise stated at thorough plea colloquy that no promises had been given as inducement to enter instant blind plea. Record also did not support defendant’s claim that his trial counsel was ineffective for failing to advise him against entering into blind plea, where defendant’s counsel had urged him to accept written plea agreement proposed by govt., and where counsel stated that defendant’s insistence on entering blind plea was against counsel’s advice.
