Key legal question
Whether the disciplinary prosecution was time-barred under the applicable law.
Extracted holding
The prosecution was not time-barred; the one-year period started when the supervisory chamber learned of the facts through the March 2004 complaint and was interrupted by investigative acts.
Extracted reasoning
For lex mitior purposes, the old Valais law was overall more favorable. Under that law, as under the federal law, the limitation period runs from the supervisory authority's knowledge of the incriminating facts, not from earlier events before any denunciation.
