Federal courts have ruled in the past that if ballot access is impossible, or virtually impossible, and a party or a candidate who wants to be on the ballot sues, and shows evidence of a modicum of support, then the court should put that party or candidate on the ballot even if it submits few if any signatures or does no other substantial work to qualify.
U.S. Supreme Court examples: (1) Eugene McCarthy was put on the Texas ballot as an independent presidential candidate in 1976 even though he did not submit any signatures. McCarthy v Briscoe, 429 US 1317 (1976); (2) the National Democratic Party of Alabama (an African-American Party not affiliated with the Democratic Party) was put on the ballot for county office in Hadnott v Amos, 394 US 358 (1969); (3) an independent US Senate candidate, Clifton Whitley, was put on the ballot by a 3-judge US District Court Judge in Mississippi in 1966, and the U.S. Supreme Court affirmed that decision with a full opinion, Allan v State Board of Elections, 393 U.S. 544 (1969); (4) several minor parties were put on the Michigan ballot in 1976 by a 3-judge U.S. District Court, and the U.S. Supreme Court summarily affirmed that decision, 430 US 924 (1977). The lower court decision cite is 419 F.Supp.1002 (e.d. 1976).
US Court of Appeals examples: (1) the Fifth Circuit put McCarthy on in Florida in 1976 even though he didn’t petition. McCarthy v Askew, 540 F 2d 1254 (back then, Florida was in the Fifth Circuit because the Eleventh Circuit didn’t exist); (2) the Sixth Circuit put a Communist Party candidate on the Michigan ballot for State Board of Education. Goldman-Frankie v Austin, 727 F.2d 603 (1984); (3) the Ninth Circuit put the Populist Party on the Idaho ballot in 1984 even though it only collected fewer than 300 signatures. Populist Party v Evans, not reported, 84-4108.
