This Georgetown Law Review article examines in detail the states' constitutional language and case law regarding redistricting timing, to chart the likely fault lines of future attempts to re-redraw district lines. It examines the states in which legislatures have unambiguous latitude to do as they please, the states in which legislatures are unambiguously limited, and the vast ambiguous middle. The article also discusses some of the most common scenarios in which disputes over re-redistricting arise, and explores their implications for how ambiguous state constitutional provisions are likely to be construed. Finally, the article offers an assessment of the effects of overly frequent redistricting, and offers some tentative conclusions about the future of efforts to address the re-redistricting controversy, in Texas and beyond.
