Article summary
This study asks whether executives exploit gaps between legislative sessions to pursue policy by unilateral action, and when legislatures can block that tactic. Using variation across US states in intersession timing, divided versus unified government, and whether legislatures control special session timing, the authors identify conditions under which governors increase executive orders during adjournments. The central contribution is evidence—drawn from state-level analysis—that intersession breaks create opportunities for executive unilateralism, but only when legislatures lack the power to call or control special sessions.
