Chadwick St. Louis v. Commissioner of Correction, 161 Conn.App. 358

Background

Petitioner Chadwick St. Louis was tried by a three-judge court for murder after the court found he struck and buried the victim with a skid‑steer (Bobcat); he was convicted and sentenced to 50 years. The conviction was affirmed on direct appeal (State v. St. Louis).
Petitioner filed an amended habeas petition alleging three ineffective‑assistance‑of‑trial‑counsel claims: (1) failure to investigate an alternative cause of death, (2) failure to present voluntary‑intoxication evidence (heroin use), and (3) failure to produce witnesses. He later added an unraised claim about plea advice on appeal only.
At the habeas trial the petitioner presented four witnesses: trial counsel, a former cellmate, his expert Attorney James Diamond, and the petitioner. The habeas court assumed deficiency but found no prejudice from counsel’s conduct and credited trial counsel over the petitioner.
The habeas court denied the amended petition and denied certification to appeal. Petitioner appealed the denial of certification and the merits ruling.
The appellate court reviewed under Simms standards (abuse of discretion to deny certification; if abuse shown, then merits review). For the ineffective‑assistance claim the court applied Strickland’s performance and prejudice tests.

Issues

Issue	Plaintiff's Argument (St. Louis)	Defendant's Argument (Commissioner)	Held
Did habeas court abuse discretion in denying certification to appeal?	Denial was improper because underlying ineffective assistance claims are debatable and deserve review.	Habeas court’s resolution is not debatable among reasonable jurists; no abuse of discretion.	Denial affirmed; no abuse of discretion.
Was trial counsel ineffective for failing to cross‑examine the medical examiner?	Expert Diamond: additional cross‑examination would have shown the examiner could not determine precise cause of death, creating reasonable doubt.	Medical examiner already testified on inability to determine cause; additional questioning would be cumulative.	No prejudice shown; claim fails.
Was counsel deficient for not objecting to testimony about the Bobcat’s potential to cause death?	Diamond: a proper objection would have weakened the state’s causation theory.	State evidence (detective testimony, police report, petitioner’s statement) already tied Bobcat to death; no habeas evidence disproving Bobcat causation.	No prejudice; claim fails.
Did counsel’s failure to investigate witnesses/ alternative theories prejudice petitioner?	More investigation would have developed an alternative theory and helpful witnesses.	Petitioner offered no specific evidence of what additional investigation would have produced; mere speculation insufficient.	No prejudice established; claim fails.
Was trial counsel’s credibility finding (over petitioner) clearly erroneous?	Petitioner contends the court erred in crediting counsel over him.	Habeas judge as factfinder entitled to assess credibility; record supports that choice.	Not clearly erroneous; credibility determination upheld.
