Institution

Delaware has only one congressional district.

Delaware’s state legislative lines are drawn by the state legislature, as a regular statute, subject to gubernatorial veto.

Timing

The legislature’s deadline for producing plans was originally June 30, 2021. Because the deadline is set by statute, the legislature may change it at any time. [29 Del. Code § 805].  On June 24, 2021, the legislature adopted a new deadline of Nov. 7, 2021 for final plans to accommodate the delay in Census data.  [H.C.R. 32] 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]

Public input

The legislature has not yet announced any specific plans or guidelines for public input.

Criteria

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]

2010 cycle

Delaware’s legislature passed a state legislative plan (HB 210) on June 30, 2011, which was signed by the Governor on July 8, 2011.

On Jan. 26, 2012, the legislature adjusted the plan somewhat with HB 250, which was signed on Feb. 3, 2012.

It appears that the plan was not challenged in court.

2000 cycle

Delaware’s legislature enacted a state legislative plan (HB 467) on Apr. 18, 2002, which was signed by the Governor on Apr. 19, 2002.

The plan was amended in minor fashion by HB 556, passed on June 18, 2002 and signed by the Governor on June 19, 2002.

It appears that the plan was not challenged in court.
