Any law that is longer than what can be read and understood by the average educated citizen in five minutes or less is an attempt to hide provisions detrimental to the public.
Well, not exactly, the SUMMARY at the end of the bill is what needs to be simple, reflective and concise.
I assume you are referring to a bill itself, an act...the actual pages of legislative language...
I would posit that every bill ever considered would not fit your parameters, for if it changes a word or adds a definition, or refers to an existing statute(s) it may change the language of ten or twenty pieces of text of the existing law-books. All of those "revisions" are required to be in the bill, making it many pages longer than the actual intent.
If you go to the back page of the bill and read the summary first (hopefully in less than five minutes) it should be fairly easy to understand. Then, if you want to pull your hair out, go back and dig into the actual confusing nuts and bolts of the bill.
Almost without fail, you will see "old language" struck-out much like happens here on FR, and the "new language" underlined. Pages and pages and pages of it.
