The Swiss government Wednesday revealed plans to settle a bitter dispute with Washington after lawmakers rejected a deal that would have halted US legal action against banks suspected of stashing cash for American tax dodgers.
Rather than a blanket accord, Swiss banks will now have to apply on a case-by-case basis for government permission to cooperate with US investigators, Finance Minister Eveline Widmer-Schlumpf said.
The moves comes two weeks after the Alpine country's parliament shot down the controversial "Lex USA" accord, which would have temporarily lifted Switzerland's long-sacrosanct banking secrecy and allow banks to settle with US authorities and draw a line under past wrongdoing.
Parliamentary backing was needed for a one-year blanket waiver of secrecy rules for American clients.
Currently, US investigators have to make formal requests for legal assistance concerning specific tax-dodgers, a procedure Washington sees as cumbersome.
The Swiss government had approved Washington's take-it-or-leave-it settlement at the end of May, with a view to having it in force this month.
But parliament had the final say, and there was uproar from lawmakers over the fact that they were asked to vote on the deal without the details being disclosed, and concerns that it breached Swiss sovereignty.
Without the blanket secrecy waiver, the individual banks need government permission to cooperate with US probes of their alleged abetting of tax evasion by Americans.
Legal cooperation is expected to include the banks paying massive fines in exchange for an end to US lawsuits.
Swiss banks are believed in the past to have accepted billions of dollars belonging to American citizens who have not declared these assets to US tax authorities, though they now refuse such money.
Under the government plan -- which will need US approval, but not that of parliament -- the banks will be able to hand over the names of employees and third parties who dealt with American clients.
In addition, they will have the right to provide "Leavers Lists" with details of sums transferred by former US clients, but not their names.
Widmer-Schlumpf said the clients' names could only be handed over if US lawmakers ratify a long-await tax treaty which has already been passed by the Swiss.
The battle began in 2009 after Swiss banking giant UBS was fined in the United States for complicity in tax evasion -- an issue in sharp focus amid the financial crisis.
