Congressional maps are enacted by the Maryland General Assembly, subject to the Governor’s veto. The General Assembly adopts legislative plans by joint resolution, not subject to the Governor’s veto. The Governor submits a proposed legislative plan that becomes law if the General Assembly fails to adopt a plan by its deadline.
Maryland’s congressional delegation remained at 8 seats following the 2020 reapportionment.
Primary Authority: The Maryland General Assembly draws and enacts congressional plans, subject to the Governor’s veto. The General Assembly can override a veto with a 3/5 vote in each chamber. Democrats currently have a veto-proof majority in both chambers.
If a bill is presented to the Governor during session, the Governor has 6 days to sign or veto it; otherwise, it becomes law without signature. If it is delivered during the last 6 days of session, the Governor must sign or veto it within 30 days of transmittal; otherwise, it becomes law without signature. Sundays are excluded from these calculations.
