The Constitution defines how the government (production of commons) is organized.
The bill of rights defines the law that may not be discovered, legislation and regulation that may not be passed.
The constitution does try to implement natural law (life, liberty, property), but it does not state such concretely in the bill of rights, nor does it state the law of reciprocity despite the fact that reciprocity is the basis for germanic common law back into pre-history.
We could quite easily reorganize the constitution life(existence), liberty(action), property(thing), and reciprocity (volition), and then tie every one of the articles and amendments back to these (reciprocity and three dimensions of its demonstration).
This set of three rights (existence, action, possession) and the single law of reciprocity are very simple criteria by which any constitution can be strictly constructed.
