17 establishments impacted by new vaccine rules filed a court case against new measures that come into force on Monday.
The new rules will limit entry to restaurants, gyms, cinemas, bars and other places to vaccinated people only.
The establishments filed the warrant of prohibitory injunction on Sunday morning. The first sitting is scheduled for 28 January.
The plaintiffs cite Constitutional clauses as well as the European Convention on Human Rights.
Such a warrant would prevent an entity from doing something that would be prejudicial to the applicant. An applicant must prove, prima facie, that their rights were prejudiced in order for the warrant to be issued.
The 17 parties are being represented by lawyers Arthur Azzopardi, Keith Borg, Eric Micallef Figallo, Clive Gerada and Franco Debono.
