norregel: a preregistered benchmark of dated numeric values in Norwegian law

The paper introduces *norregel*, a preregistered benchmark that tests language models on numeric values in Norwegian legal texts, including amounts, percentages, and age limits, each tied to a specific date. The benchmark contains 916 items extracted from Lovdata, allowing answers to be classified as correct, outdated, wrong, or uninterpretable. Two preregistered runs were conducted: the first showed mixed results across five models, while the second, involving eight models, supported the hypothesis that outdated answers are more common for values introduced after a model’s cutoff, though the robustness of this finding varied across sensitivity analyses.
