A referendum on a new constitution was held in Guam on 8 August 1987. Instead of passing the whole constitution as a unit, voters chose to approve each chapter of the document individually. With a low turnout of 39%, all chapters were approved except for Chapter I on relations with the United States and Chapter VII on Chamorro relations and immigration. Modified versions of these rejected chapters would be accepted in a referendum later the same year.
November
A referendum on chapters of a constitution was held in Guam on 7 November 1987. Chapter I (on relations with the United States) and Chapter VII (on Chamorro relations and immigration) had been rejected in a referendum in August, and the Constitutional Commission resubmitted modified versions. Both modified versions passed on the back of a much higher turnout of 58%.
