The ruling matters because Swiss banks are among the world’s most international. They employ thousands of private bankers offshore, and many more in outsourcing operations in countries like India and Poland. Many foreign employees are involved in creating structures comprising overseas companies and trusts linked to a Swiss bank account. Thanks to the ruling, as long as their employment contract is local they can now leak information on suspected tax evasion or other shenanigans without fear of falling under Switzerland’s draconian secrecy law, which imposes jail terms of up to five years on whistleblowers.
