Very important: There is no de facto "standard" legal state of uninhabited and unclaimed land. Both constitutions and monarchies are choices. They can (and should be) legitimized by a souvereign. You could argue that once people live on mars, they can choose to establish some sort of council that designs a constitution. By the way, constitutions are typically informed by existing law, so it is plausible to assume that any mars constitution would resemble the (modern) ones we have. [edit] To add: Of course anybody can claim some constitutional basis to exist, but everyone can challenge that. See Russia's occupation of the Krim peninsula, which quickly turned into a legal battle regarding souvereignity.
