Vienna, June 02, 2026

The Austrian Constitutional Court (Verfassungsgerichtshof, VfGH) will hold a public hearing on June 22 to examine the appeal filed by the FPÖ and the Greens against the messenger surveillance law.

The hearing follows the submission of a Drittelbeschwerde (one-third appeal) signed by 62 deputies from the FPÖ and the Greens, two parties in the Austrian opposition, who question the constitutionality of the law approved in early July of last year by the National Council (Nationalrat). With this procedural mechanism, at least one-third of the members of Parliament can request the Constitutional Court to review an already approved law.

The law empowers authorities to install surveillance software on private devices to monitor messaging services, a measure that the appellants consider a technically powerful instrument with enormous potential for abuse. The plaintiffs describe the tool as a "technisch derart mächtiges Instrument" and warn that the software necessary for surveillance cannot be legitimized by the state "schon per se."
