Legislative Intent Service was started by Tom Stallard and Bill Keller following their employment in the California Legislature. Responding to the needs of numerous frustrated telephone callers seeking legislative information, they recognized the need for an organized system for retrieval of legislative documentation, combined with the provision of specific and well-crafted explanations to allow lawyers and others the opportunity to make effective use of these esoteric materials. They founded Keller & Stallard, which does business as Legislative Intent Service.

That was in 1974. Today, lawyers and the Courts themselves have come to rely on Legislative Intent Service as the authoritative source for legislative documentation. In fact, Legislative Intent Service is cited in more than 50 appellate opinions.
