SC20433 - Cookish v. Commissioner of Correction (“The habeas court, acting sua sponte and without providing the petitioner with notice or a hearing, dismissed the habeas petition pursuant to Practice Book § 23-29 for lack of jurisdiction. The habeas court determined that dismissal pursuant to § 23-29 (1) was warranted and that the petition should be returned because it was apparent, on the face of the petition, that the petitioner was not in custody for the conviction being challenged. On appeal, the petitioner asserts that the habeas court improperly (1) dismissed the petition under § 23-29 without first appointing him counsel and providing him with notice and an opportunity to be heard, and (2) failed to construe the habeas petition as a petition for a writ of error coram nobis.”)
