The postponement was also done to allow the United Nations team time to conduct fact-finding mission in North Borneo (now Sabah) and Sarawak regarding the two states participation in a new federation.
Penundaan ini juga dilakukan agar Perserikatan Bangsa-Bangsa dapat melakukan referendum di Borneo Utara (kini Sabah) dan Sarawak mengenai partisipasi mereka dalam federasi baru.
