Abstract
The second supplementary budget of 2021 at the federal level was declared null and void by the Federal Constitutional Court in November 2023. The decision has an impact on the state of Baden-Württemberg as the state-level debt brake regulations have been in force since 2020. The state has legitimised a total of around 14.8 billion euros in borrowing in the 2020 and 2021 financial years. In this respect, Baden-Württemberg has violated the principle of annuality by transferring unneeded credit authorisations in the reserve for budgetary risks between financial years. In addition, deferred borrowing in Baden-Württemberg is steadily increasing. Consequently, the state needs to take budgetary action to reduce its debt and comply with the budgetary principles.
