Key legal question
Whether the mutual legal assistance request was abusive because it allegedly concealed a fiscal case and sought evidence for tax proceedings.
Extracted holding
The request was not abusive; it mainly alleged a common-law asset injury through receipt of hidden commissions, and the specialty reservation barred use for tax proceedings.
Extracted reasoning
The request did mention non-declaration in tax returns, but its core allegation was self-enrichment and damage to the shipyard. The Swiss authority expressly reserved specialty and prohibited any fiscal use, so the tax reference did not invalidate assistance.
