Another poster and I have been quoting from the FAA Special Conditions for the A320. These have followed the normal FAA process of rulemaking. A Notice of Proposed Special Conditions was published in the Federal Register on October 19, 1987. The comments received from the public in response to that notice are discussed in the preamble of the final rule. Regarding the reference stall speed the A320 Special Conditions are largely identical to the current standard of the regulation, proposed in 1995 and adopted in 2002 with FAR Amendment 25-108.
Many people from airworthiness authorities, manufacturers, operators and pilot associations in the U.S., Canada and Europe participated in the development of those changes in the regulations. In fact it would be difficult to identify a manufacturer of transport category airplanes or its regulatory agency that was not involved in that process. I doubt that any of those individuals would have claimed to be 'in charge of that work'.
