Controversial Swiss People’s Party MP Christoph Blocher says he might appeal to the Federal Supreme Court a parliamentary committee decision to deny him immunity in a case of alleged violation of banking secrecy. 

Blocher hit back at the Council of States legal committee just after the decision that Blocher did not have immunity while passing along bank data before or after his swearing in as an MP.

The bank data pertained to former Swiss National Bank Chief Phillip Hildebrand.

Blocher said an MP should be able to defend himself when treated like that, and that it was a political decision—even unconstitutional.

He then admitted the court would likely not want to interfere in legislative business, but it seems Blocher is content with buying time.

He alleges he has five days to request criminal proceedings against him be halted, after a prosecutor had to recuse himself for talking about the case in a bar.

Committees in both houses of Parliament agree Blocher does not hold immunity in the case.

Previously, there was some question whether passing along documents showing currency transactions from Hildebrand’s accounts qualified as parliamentary business.

Zurich prosecutors can now proceed with a case against Blocher for alleged breach of banking secrecy laws.
