Question juridique clé
Whether the disciplinary matter should be judged under the former Lucerne cantonal lawyer act or the later Federal Lawyers Act.
Solution extraite
The cantonal law had to be applied because the federal act was not the milder law in the concrete case.
Motifs extraits
The alleged conduct would be disciplinarily punishable under both regimes, but the federal act was not more favorable because the relevant sanction framework, especially the higher maximum fine, was not milder in the concrete circumstances.
