Key legal question
Whether mutual legal assistance could be refused because the Swiss limitation period had expired for the alleged conduct.
Extracted holding
The Swiss limitation period was relevant in principle only as a discretionary ground under the treaty, but the cantonal authorities did not abuse their discretion by not refusing assistance.
Extracted reasoning
The treaty aimed to promote assistance as far as possible; Swiss jurisprudence and doctrine restrict the role of limitation in MLA; the offence was time-barred in Switzerland, but Art. 2(1)(d) RVAUS is optional and Art. 5 IRSG does not override the treaty.
