In Katz v. Fitzgerald (1907) 152 Cal. 433, the California Supreme Court upheld the percentage restriction of former section 1361 of the Political Code, stating at page 436 as follows: "Some classification is made necessary, else any two, three, or four men might call themselves a party and impose the burden of placing the names of their candidates upon the ballot provided by the state law -- a condition which could easily be made intolerable to the state as well as to the voters."
