On October 4, 1862, a Treaty was signed between Belgium and the Hawaiian Kingdom in Brussels and thereafter ratified by both governments. Article IV of this treaty provides:
“the respective citizens of the two countries shall enjoy the most constant and complete protection for their persons and property. Consequently they shall have free and easy access to the court of justice in the pursuit and defense of their rights in every instance and degree of jurisdiction established by the laws.”
Neither Belgium nor the Hawaiian Kingdom gave notice to the other of its intention to terminate this treaty in accordance with the terms of Article XXVII of the 1862 Treaty. Therefore this treaty is still in full force and continues to have legal effect to date. Former Belgian territories, which acquired their independence from Belgium, are successor States to, at the very least, Article IV of the Hawaiian-Belgian Treaty with regard to the citizenry of the successor State that effectively replaced the citizenry of the predecessor State in the treaty. These successor States are:
- Democratic Republic of the Congo. Independence: June 30, 1960.
- Burundi. Independence from Belgian Trusteeship on July 1, 1962.
- Rwanda. Independence from Belgian Trusteeship on July 1, 1962.
