i think having a judiciary system to start is (kinda) understandable.. but you have to think.. who controlled law at that stage in human civ? probably the trible leader (or shaman if we pick a civ that starts with mysticism) so i think we should have only one judiciary position untill our civ evolves beyond rocks and 10 turn road construction

.. and as for a constitution.. we should have that as an unspoken background agreement untill we actually get *constitution*

.. i just kinda see all this being too advanced and well thought of for cavemen and nomads to immediately adhere to and follow unerringly.. but oh well.. these are just my thoughts,
peace,
