Here is a look at one example of changing a recall law to limit recalls. In 1971, two Idaho legislators (from the same area, Idaho Falls) were ousted in recalls, Senator Fisher Ellsworth and Assemblyman Aden Hyde. The recall was focused on a pay raise.
According to this article, the following year the legislature revised the recall law from 20% of turnout for the governor in the district to 20% of registered voters. This made a recall much less likely to occur (according to the piece, the legislature also junked a voter-approved term limit law).
