Meanwhile, Austria is set to discuss a draft law that would allow a new security agency to operate with reduced external control and to collect and store communication data for up to six years. The Netherlands is considering legislation allowing dragnet surveillance of all telecommunications, indiscriminate gathering of metadata, decryption and intrusion into the computers of non-suspects. And in Finland, the government is even considering changing the Constitution to weaken privacy protections in order to ease the adoption of a bill granting the military and intelligence services the power to conduct electronic mass surveillance with little oversight.

Governments now argue that to guarantee our security we have to sacrifice some rights. This is a specious argument. By shifting from targeted to mass surveillance, governments risk undermining democracy while pretending to protect it.

They are also betraying a long political and judicial tradition affording broad protection to privacy in Europe, where democratic legal systems have evolved to protect individuals from arbitrary interference by the state in their private and family life. The European Court of Human Rights has long upheld the principle that surveillance interferes with the right to privacy. Although the court accepts that the use of confidential information is essential in combating terrorist threats, it has held that the collection, use and storage of such information should be authorized only under exceptional and precise conditions, and must be accompanied by adequate legal safeguards and independent supervision. The court has consistently applied this principle for decades when it was called to judge the conduct of several European countries, which were combating domestic terrorist groups.

More recently, as new technologies have offered more avenues to increase surveillance and data collection, the court has reiterated its position in a number of leading cases against several countries, including France, Romania, Russia and Britain, condemned for having infringed the right to private and family life that in the interpretation of the court covers also “the physical and psychological integrity of a person.”

Last year, the European Court of Justice set limits on telecommunication data retention. By invalidating a European Union directive for its unnecessary “wide-ranging and particularly serious interference with the fundamental right to respect for private life” and personal data, this court reaffirmed the outstanding place privacy holds in Europe. This judgment echoed a 2006 German Constitutional Court ruling that the German police had breached the individual right to self-determination and human dignity after they conducted a computerized search of suspected terrorists.
