v.
Cahan,
While a writ of mandate may, in a proper case, be used to correct an abuse of judicial discretion, it cannot be used to control a discretionary act of a superior judge. In particular, the writ may not be used to compel a judge to admit or exclude evidence during a trial, even if such ruling is an erroneous one. It is elementary that a trial judge has the jurisdiction to decide matters before him erroneously as well as correctly. That is one reason why we have appellate courts. A ruling on the admission of evidence, even if wrong, is not an abuse of discretion but simply an erroneous ruling.
That mandamus will not issue in such cases is well settled in this state.

Notes
Petitioner argues quite forcefully that the search here was one incidental to a lawful arrest and therefore not illegal.
