Abstract: The article examines the significance of Diocles’ Law (Dem. 24.42) for the growing problem of (in)validity of laws in the Athenian legal order in the late fifth century BCE. Diocles’ Law should be understood as part of the broader set of vital principles that constituted an ‘evolving law reform’ aimed at consolidating laws and strengthening the rule of law and democracy after deep constitutional crises. This study reconstructs the factual and legal background to which specific clauses of Diocles’ Law refer (sections 2.1–2.4; ἐν δημοκρατίᾳ, κυρίους εἶναι, the archonship of Eucleides, ἀναγεγραμμένοι). More broadly, it outlines the challenges the Athenians faced at that time, and the measures they took to address them, arising not only from the two oligarchic coups d’état, but also from mounting problems in their legal, constitutional, and judicial order. The article also argues that an analysis of Greek legal language – and its manoeuvrings as seen in Andocides’ On the Mysteries – confirms that issues of the validity (κυρίους εἶναι) of laws must be distinguished from those concerning their application (χρῆσθαι). Even though the latter also played a role at the time, especially due to the caesura marked by the archonship of Eucleides (403/2), the central argument is that Diocles’ Law was enacted to impose order specifically on the validity of laws at a very particular historical moment. This law was relevant retrospectively to ‘the
scrutiny of the laws’, with the vital involvement of ἀναγραφεῖς τῶν νόμων from the beginning of their work in 410, and, more broadly, to future lawmaking. In addition (section 3), the article eventually identifies the principle of ‘legal certainty’, which underpinned the introduction of Diocles’ Law, and formed a key part of Athenian legal culture at the end of the fifth century BCE.
