Two constitutional referendums were held in Guam in 1987.
In the first on 8 August 1987,[1] voters were asked 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[2] and Chapter VII on Chamorro relations and immigration.
[3] Amended versions of the two rejected chapters were brought back for voters to approve on 7 November 1987.
Both modified versions passed on the back of a much higher turnout of 58%.
