State v. Diaz , 1989 Me. LEXIS 85 ( 1989 )

COLLINS, Justice.

Jody Diaz appeals from his conviction by a Superior Court jury (Penobscot County; Silsby, J.) of operating under the influence or with excessive blood alcohol in violation of 29 M.R.S.A. § 1312 (1983 and Supp.1987) (Class D).

Because we are reviewing for obvious error, we do not find that the prosecutor’s improper closing comments concerning Diaz’s expert witness warrant vacation of the judgment.¹ State v. Dube, 522 A.2d 904, 907 (Me.1987). Regrettably, however, we once again find it necessary to remind the State of its overriding obligation to see that an accused receives a fair trial, State v. Pineau, 463 A.2d 779, 781 (Me.1983), and admonish against the use of personal opinions concerning a witness’ credibility. M.Bar.R. 3.7(e);² State v. Pendexter, 495 A.2d 1241, 1241 (Me.1985).

Furthermore, because evidence in the record supports the presiding justice’s determination that the intoxilyzer tests are “sufficiently reliable,” we reject Diaz’s contention that admission of the results into evidence constitutes an abuse of discretion. 29 M.R.S.A. § 1312(6); State v. Taber, 474 A.2d 877, 878 (Me.1984). Finally, in the absence of any objection by Diaz to the jury instructions, we fail to find “obvious error affecting substantial rights.” State v. True, 438 A.2d 460, 467 (Me.1981).

The entry is: Judgment affirmed.

All concurring.

[The Defendant's expert] came in here and he told you just what this man wanted him to say ... he could care less what the facts were.
