In Michael Patrick Pimentel v. Mendocino County, Judge Davila denied Pimentel’s petition challenging his conviction, finding no constitutional violation by his trial lawyer.
Michael Patrick Pimentel’s state convictions remain in place, and his federal petition for relief was denied. Mendocino County was the named defendant.
What happened
Michael Patrick Pimentel v. Mendocino County concerns Pimentel’s petition asking a federal court to overturn his California convictions for driving under the influence and driving with an excessive blood-alcohol level. He argued that his trial lawyer should have challenged a prosecutor’s statement that his blood-alcohol level was “150 times the legal limit.”
Pimentel’s lawyer did not object to the statement or correct it during closing argument. Pimentel argued that the statement damaged his defense that the breath-test results were unreliable, especially because the actual result was 0.12 percent and the legal limit was 0.08 percent.
Judge Edward J. Davila denied the petition. The judge ruled that the lawyer’s decision not to object could reasonably have been a trial strategy and that Pimentel had not shown the statement probably changed the verdict. The court also said that no certificate allowing an appeal would issue.

Background
Pimentel sought federal review of his California conviction under 28 U.S.C. § 2254, the federal law allowing a state prisoner to challenge a conviction in federal court. The opinion states that he was convicted of driving under the influence of alcohol and driving with a blood-alcohol level of at least 0.08 percent. He received a sentence of 48 hours in county jail and 36 months of probation.
The first trial ended in a mistrial after the jury could not reach a verdict. At the retrial, the jury unanimously found Pimentel guilty of both counts. The Mendocino County Superior Court’s appellate division upheld the judgment, and the California Court of Appeal denied Pimentel’s request to transfer the appeal.
Pimentel’s claim
Pimentel argued that his trial lawyer provided ineffective assistance of counsel, violating his Sixth Amendment right to counsel. During closing argument at the retrial, the prosecutor said that Pimentel’s two 0.12-percent blood-alcohol results were “150 times the legal limit.” The lawyer did not object to or correct that statement.
Pimentel argued that the statement harmed his defense that the breath tests were unreliable. He contended that describing his blood-alcohol level as “150 times the legal limit” could have made the jury view the results as too high to be explained by faulty testing.
Legal standard
The court applied the Antiterrorism and Effective Death Penalty Act of 1996, which requires a federal court to give substantial deference to a state court’s decision. Under the two-part test from Strickland v. Washington, a defendant must show both that counsel’s performance fell below constitutional standards and that the error probably affected the result. In federal review of a state conviction, the court described this as a doubly deferential inquiry: the federal court gives deference both to the state court and to the defense lawyer’s judgment.
Court’s analysis
The court held that Pimentel’s lawyer’s failure to object did not satisfy the performance part of the test. It began with the presumption that the lawyer’s decision could have been a reasonable strategic choice. Objecting might have drawn additional attention to the prosecutor’s mistake and led the prosecutor to redo the calculation and emphasize that Pimentel’s blood-alcohol level still exceeded the legal limit.
The court also noted that the trial judge instructed jurors that lawyers’ statements were not evidence and that they should rely on the trial record if a lawyer’s statement conflicted with the evidence. The trial testimony consistently identified the evidentiary breath-test result as 0.12 percent. The court concluded that the state court reasonably determined that the lawyer’s decision not to object was within the range of reasonable professional conduct.
The court separately held that Pimentel failed to show prejudice. The evidence included his admission that he had consumed two beers, a half-empty bottle of Hennessey, preliminary test results of 0.135 and 0.13 percent, and evidentiary breath-test results of 0.12 percent. The prosecution only had to prove that his blood-alcohol level was above 0.08 percent; it did not have to prove any multiple of that limit. The court therefore found it unlikely that the prosecutor’s single misstatement caused the guilty verdict.
The court rejected Pimentel’s argument that the different outcomes at the two trials showed that the misstatement caused the guilty verdict. It stated that the trials involved different juries and that determining whether the new jury or the prosecutor’s statement caused the different result would be speculation, which was insufficient to establish prejudice.
Disposition
The court DENIES Pimentel’s petition for a writ of habeas corpus. It also states that no certificate of appealability shall issue because reasonable jurists would not find the court’s assessment of the constitutional claims debatable or wrong.
