Key legal question
Whether the validity and admissibility of pre-StPO evidence had to be assessed under cantonal law or the Swiss Criminal Procedure Code
Extracted holding
Pre-StPO procedural acts and the admissibility of evidence obtained through them remain governed by the former cantonal procedural law; the cantonal court did not violate federal law by applying Thurgau procedure.
Extracted reasoning
Art. 448 StPO preserves the validity of pre-entry procedural acts and, by extension, their evidentiary consequences. Ongoing cases are continued under the new code, but earlier measures remain assessed under the old law.
