Should the first settlement on Mars be allowed to make its own laws?

Imagine the first permanent settlement on Mars: a few hundred people, months from Earth, sent and supplied by countries and companies back home. Who should write the rules they live by? A thought experiment about a future that space agencies and companies are planning for.

Side A: Their own laws

People living months from Earth, in danger every day, must be able to make the rules they live by. Earth cannot govern from twenty minutes away.

Side B: Earth's laws

Settlers are sent, supplied and rescued by countries on Earth. Those countries stay responsible, so their laws have to apply.

What the law says: The countries on Earth stay responsible

• International law · Outer Space Treaty (1967): No country may claim Mars as its territory. Countries are internationally responsible for their national activities in space, including those of private companies, which need their authorisation and continuing supervision. A country keeps jurisdiction over the spacecraft it registers and the people on board.
• Still open: No treaty yet says how a permanent settlement would govern its own daily life.
