Amendments to the Constitution.
The Public Will Always Govern
The Constitution must be amenable to change, but only upon sustained demand by a large majority of the public. Amendment Referendums must be proposed by at least five percent of the voting public or proposed by eighty percent of the Executive Council. For an amendment change to the Constitution to appear on an Amendment Referendum it must first be approved by a majority of sixty percent in a National Poll.
Constitutional Amendments are only approved if passed by a seventy-percent majority in an Amendment Referendum. To ensure that the Constitution is not changed due to a temporary whim of the public, such decisions are subject to a second referendum held two years later. It becomes law only if confirmed again by sixty percent of the vote. Any Constitutional Law can be amended once within any ten-year period.
Evidently, these rules restrict the power of the public to make changes. Of course, these rules as well as the rest of the Constitution must be themselves approved by the public in the first place. It is likely that the public will accept restraints for the sake of stability.
Life evolves and society follows. Laws must be a solid framework for society, but not an obstacle to progress. The system must be flexible, though not fickle. Laws represent the codified will of past times, and they must be changeable. The ultimate authority must be the public will as it prevails at any time.
