Delaware’s state legislative lines are drawn by the state legislature, as a regular statute, subject to gubernatorial veto.
The legislature’s deadline for producing plans is June 30, 2021, though this deadline is set by statute, and may be altered by the legislature. [29 Del. Code § 805]. Candidates must file for state legislative primary elections by July 12, 2022. [15 Del. Code § 3101(1)]
The legislative session began on Jan. 12, 2021, and is currently scheduled to end on June 30, 2021.
Delaware also prohibits redrawing lines mid-decade, before the next Census; this constraint is also set by statute, and may be altered by the legislature. [29 Del. Code § 805]
The legislature has not yet announced any specific plans or guidelines for public input.
Like all states, Delaware must comply with constitutional equal population requirements, and state statutes further specify that districts must be “nearly equal in population.” Delaware will also adjust census data in order to count incarcerated individuals at their last known residence before incarceration. [29 Del. Code §§ 804, 804A]
Delaware must also, like all states, abide by the Voting Rights Act and constitutional rules on race.
State law further asks that state legislative districts be, insofar as possible, contiguous and bounded by roads, streams, and other natural boundaries. Districts may not be drawn to unduly favor any person or political party. The legislature may alter these statutory requirements as it wishes. [29 Del. Code § 804]
