On May 12, the Alabama Secretary of State said primaries will be held for U.S. House districts 1,2,6, and 7 on Tuesday, August 11. This automatically sets the petition deadline for minor party and independent candidate petitions for those races on that same August 11 day.
Under several precedents that apply to Alabama, the state must cut the number of signatures from the normal 6,000 signatures, to 12.3% of the normal number. Thus the average number of signatures for this year’s petitions for U.S. House would be approximately 738 signatures.
Here is the Secretary of State’s announcement. It says petitions for minor party and independent candidates are due August 11 at 5 pm, but he says nothing about how many signatures will be required. Under Hall v Merrill, 212 F Supp 3d 1148, the state must reduce the number of signatures.
