Intent of the law might be a better term, but it is clear that intent of the law makers does matter when it comes to court cases trying to decide the actual extents a law can be applied. Even the most legalese specific law can have major gaps depending upon how you read certain words. I've read court cases where judges had to go back to when a law was written, look at other laws, look at how the law was originally applied, and then take this all into account when determining if a specific action was legal or not under such a law.
