"Quo warranto": only in California--challenging early chiropractic law.

In California from 1907-1925 two writs of quo warranto were filed against the first two chiropractic boards. Thirteen of the fifty original medical practice acts and at least eleven original chiropractic acts contained an eligibility requirement for first appointed board members, a stipulated pre-practice period. Twenty-three of these combined boards suffered no legal challenges by practicing colleagues, the attorney general or the courts, for what appeared to be unlicensed practice. Only in California were the first two boards so challenged. In California, there were other unique forces at work that no chiropractor suspected would prematurely expunge the first appointed board. These legal quagmires delayed the systematic licensing for many months. Only in California did this unique history take place.
