Second, the results of the breath test in Davenport were reported in the officer’s sworn report on a 367 form and the court relied on the sworn report to provide the foundation.

1978It is true that In re Newbern, supra, 55 Cal.2d 508, 513 , states: “The denial of an opportunity to procure a blood test on a charge of intoxication prevents the accused from obtaining evidence necessary to his defense and is a denial of due process of law entitling him to his discharge.” (Italics added.) This rule, however, has been substantially limited by People v. Hitch, supra, 12 Cal.3d 641 , in the situation where a chemical test for blood alcohol has actually been performed but the defendant is denied the opportunity of challenging the validity of the test by intentional but good faith
