Valuation of disputed amount for rent payment and negative declaratory claims regarding invalid rent increases

The Federal Court of Justice amended its prior decision to fix the disputed amount for the revision instance at €28,486.36, calculated by adding the monetary claim for €11,880.40 to the declaratory relief value of €15,613.96 (42 monthly payments × €395.38). This procedural ruling concerns a tenancy dispute where the plaintiff sought payment of outstanding rent and a negative declaratory judgment that specific rent increases were invalid. The court determined the value in dispute by aggregating the cash demand with the value of the declaratory relief, which was assessed based on the monthly savings from the voided rent increases.
