How this law is officially changed

Solon does not know this law's official route yet. The proposal is recorded all the same, and the route appears here once its source is added.

A proposal here is not law. Support on Solon is evidence that people want the change; the official route says what it takes to make it law.

Think it through

Ask what your change would do, who would gain and who would bear a cost, and where something like it is already law. The assistant reads your draft as it stands, cites the law and the studies it finds, and takes no side. What you file stays yours.
