John K. Botson, Petitioner v. Municipality of Anchorage, Respondent

Summary

The court affirmed Botson’s DUI conviction, holding that the breath-test result was admissible despite an uncompleted external-standard check because the Municipality substantially complied with approved testing methods and the error did not undermine reliability. The court also held that Botson knowingly and intelligently waived his due-process right to an independent chemical test because he understood the basic nature and purpose of that right.
