Which of the following statements about the people-initiated referendum in the new constitution is incorrect?

The statement that the people-initiated referendum can be called after 6 years is incorrect. In the context of the Cayman Islands' constitutional framework, a referendum can be initiated within a specific timeframe, typically aligned with opportunities provided by the constitution or electoral process.

The other statements are accurate regarding referendums. They do clarify the purpose of the referendum, which is focused on legislative changes, aligning with the interests of the voters. Additionally, the requirement for a certain percentage of voter support is essential, as it ensures any decisions made through referendums reflect a significant consensus among the electorate. Furthermore, the references to addressing constitutional amendments highlight the crucial role that these referendums play in the governance and evolution of the nation’s legal framework. Thus, A is the statement that does not accurately reflect the established rules surrounding the referendum process.
