About Rudolf Elmer
Born 1955. Rudolf Elmer is a Swiss banker, statutory auditor, bank officer and whistleblower, known for Federal Act on Banks and Savings Banks and WikiLeaks.
Rudolf Elmer (born 1 November 1955) is a Swiss private banker, whistleblower, and activist. He worked as a banker at Julius BĂ€r from the 1980s to his dismissal in 2002. At this time, he was head of the bank's Caribbean operations for eight years. In 2005 he was arrested by ZĂŒrich authorities and held for 30 days as Swiss authorities alleged he unsuccessfully attempted to disclose client information.
In 2008, Elmer allegedly disclosed confidential bank documents to WikiLeaks detailing the activities of Julius BĂ€r in the Cayman Islands and its role in alleged tax evasion. In January 2011, he was convicted in Switzerland of breaching the country's secrecy laws. He was rearrested immediately thereafter for having again distributed illegally obtained data to WikiLeaks. Julius BĂ€r as well as select Swiss and German newspapers alleges that Elmer has doctored evidence to suggest the bank engaged in tax evasion.
Julius BĂ€r Elmer worked in Julius BĂ€r's ZĂŒrich offices until he was fired for stealing documents in 2002. Elmer was hired by Swiss bank Julius BĂ€r during the early 1980s as a private banker in their ZĂŒrich offices. He worked at the bank as a private banker throughout the 1980s and 1990s before leading the bank's Caribbean operations from 1994 to 2002. In late 2001, Julius BĂ€r internal security discovered that internal data had been stolen and required that every employee take a lie detector test for involvement. Elmer did not take the test the first time around due to his health and then later failed. He was then released from employment on these grounds, although he was still in possession of backup copies of data. According to the bank it was "data theft committed with criminal intent". After his resignation, he sent documents to various media, whereupon the bank called for an investigation of him and his family. In 2005, Elmer sold a Swiss business newspaper a CD with 169 megabytes of customer data, but was arrested shortly afterwards in Zurich on suspicion of violating Swiss banking secrecy law. He sat 30 days in custody. Soon after his parole he started a website for whistleblowers.
On 3 March 2008 the German magazine Der Spiegel revealed that Elmer was the source of documents that appeared some weeks earlier on WikiLeaks; Der Spiegel referred to them as partly authentic and partly fake. A California judge had the service provider of WikiLeaks block the site's domain (wikileaks.org) on behalf of Julius BĂ€r on 18 February 2008. According Swiss television documentary show Rundschau, Elmer accused his bank of evading taxes by declaring bank work to have been carried out in the Cayman Islands, whereas the work was actually done in Switzerland. In 2008, Elmer released internal bank documents with customer data and other sensitive details to the Wikileaks website. According to these allegations, Julius BĂ€r held their customers funds by funneling through investment frameworks of offshore accounts to increase profits for themselves and circumvent the Swiss tax authorities. A month later, Elmer stated in court that the disks were empty and thus contained no bank customer data.
First trial
On 19 January 2011, Elmer was ordered to answer before the Zurich District Court for breach of banking and business secrecy laws as well as a charge of coercion. The prosecutor demanded a prison term of eight months without parole and a fine of 2,000 Swiss francs. Elmer was sentenced to probation for a period of two years and fined about 5,600 euros on multiple counts of attempted coercion, threats and breaching of banking secrecy. He also was ordered to pay three-quarters of the court fees in the amount of 5,000 francs (about 3,900 euros). The presiding judge believed that Elmer had not become a whistleblower for ethical reasons, but for personal revenge: "You were for many years part of the banking world and have benefited from it." After he left court he was re-arrested in connection with handing data to WikiLeaks only two days earlier, a move that was described by the prosecutor of the first case as contempt of court. On 25 July 2011, Elmer was set free.
Second trial Elmer alleged that Julius BĂ€r noted activities done in Switzerland as if they were done in the Cayman Islands. On 17 November 2011, an appeal hearing was held at the Supreme Court of the Canton of Zurich. The Court made no judgment and sent the indictment back to the prosecutor and that it must review the investigation and supplement if necessary. As justification, the court stated that besides Elmer and the Bank, no one knew if this data actually existed in reality on the disks. It was difficult to decipher what data was actually on the disks. The judgment depends on whether the data from Swiss customers are from Switzerland, or those of the Cayman Islands, where the Swiss banking secrecy rights could not be applied. Thus, the bank was asked to explain the exact content of the CDs, which it had not done before.
Furthermore, the court found that there was insufficient evidence that Elmer authored a "significant threat" against a legal services employee of the bank. In an e-mail from Mauritius, the sender threatened the employee, and claimed he was a killer and recognized him. It was not enough that Elmer had then lived and worked in Mauritius. It must be clarified where the email was sent directly from and who sent it. It is up to the prosecutor to obtain the necessary evidence. In May 2012, the Zurich High Court ruled in an interim decision that three CDs that Elmer is said to have sent to the tax authorities or the business newspaper "Cash" may be unsealed and evaluated by the prosecution. The bank renounced the possibility of lodging an appeal against this decision.
Supreme Court of Switzerland The criminal chamber of the Federal Court on 10 October 2018 - after a public hearing before judges (lasting 150 minutes - without the parties present) - by 3 votes to 2 gave a groundbreaking judgment of acquittal in the case of Rudolf Elmer regarding violation of bank secrecy, and other matters. Most importantly, the charge of violation of Swiss bank secrecy alleged against the well-known whistleblower Elmer brought by the Higher Prosecution Office of the canton of Zurich was rejected by the Federal court and the acquittal of Rudolf Elmer by the High Court of the Canton of Zurich was confirmed. The Federal Court also upheld the complaint by Rudolf Elmer concerning the imposition of an advance payment for the release of confiscated data and documents as well as the modalities for the return of the personal data of the Elmer family. His complaint against the imposition of three-quarters of the costs of the case, including the investigation costs, in the amount of CHF 320,000, and against the penalty for convictions for document forgery and threatening behaviour, were rejected by the Federal court.
Impact The Swiss newspaper Der Sonntag wrote in a December 2010 article that Elmer had confessed to threatening to kill several bank employees. Elmer said: "I have certainly made mistakes. My emotions have been out of control."
In July 2012, the Swiss Press Council received a complaint from Elmer on the weekly magazine World Week (WW). Journalist dubbed Elmer as a "thief" and "blackmailer" and sought to confront him.
