The Law of the Splintered Paddle, or Kānāwai Māmalahoe, is an edict proclaimed by King Kamehameha I in the late 18th century ordering that the elderly, women, and children be allowed to travel and rest in safety. Hawaii wrote it into Article IX, Section 10 of its state constitution in 1978, where it stands today as a declaration of the state’s commitment to public safety rooted in Native Hawaiian tradition.
Where It Came From
The law traces back to a raid in 1782. During an attack on the village of Paʻaʻi in the Puna district of the Big Island, the young warrior Kamehameha chased a group of villagers and caught his leg in the rocks, leaving him stuck and defenseless. One of the villagers struck him over the head with a wooden paddle so hard that the paddle shattered. Kamehameha nearly died.
He survived, and over time came to see that he had been the aggressor. The people he had chased were not warriors. They were fishermen defending their families, and he had no business threatening them.
The formal law came years later, around 1797, after Kamehameha had unified the Hawaiian Islands under his rule. Speaking now as king rather than regional chief, he proclaimed the Kānāwai Māmalahoe as binding throughout his kingdom. The name itself, meaning “splintered paddle,” keeps the lesson attached to the law: a reminder of the moment a powerful leader learned restraint the hard way.
What the Law Says
The core command is short: “Let every elderly person, woman, and child lie by the roadside in safety.”
The image is pointed. Lying by the roadside is the most exposed position a person can be in, and the edict says that even then, those without power should have nothing to fear from those who hold it. The law was aimed at warriors and chiefs, not at common criminals. Its message to anyone with authority or armed strength was that none of it gave them the right to harm people who were not part of the fight. A presidential proclamation issued for King Kamehameha Day later described the edict as a law that “protects civilians in times of war.”
Its Place in the Hawaii Constitution
The Law of the Splintered Paddle might have remained a historical artifact if not for the 1978 Hawaii Constitutional Convention. Delegates, influenced by the Hawaiian Renaissance movement and including significant Native Hawaiian representation, pushed to embed Hawaiian cultural values directly into the state’s governing document.
The result was Article IX, Section 10, which reads in full:
“The law of the splintered paddle, mamala-hoe kanawai, decreed by Kamehameha I—Let every elderly person, woman and child lie by the roadside in safety—shall be a unique and living symbol of the State’s concern for public safety. The State shall have the power to provide for the safety of the people from crimes against persons and property.”
Because the language sits in the state constitution, it carries the highest legal authority Hawaii can grant. No ordinary statute can override it, and changing it would require a constitutional amendment.
What the Constitutional Provision Can and Cannot Do
The legal effect of Article IX, Section 10 is narrower than the dramatic language suggests, and the distinction matters. The provision calls the law “a unique and living symbol” and says the state “shall have the power to provide” for public safety. That is a grant of authority. It is not a command.
In practical terms, the provision likely does not create an enforceable individual right. A crime victim generally cannot sue the state under Article IX, Section 10 on the theory that the constitution required the government to prevent the harm. What the section does is empower the legislature to pass public safety laws and fund protective programs. The specific policy choices remain with elected officials.
The symbolic weight is still real. Legislators drafting public safety statutes, judges reviewing government conduct, and agencies setting priorities all work under a constitutional text that explicitly links public safety to one of the oldest humanitarian principles in Hawaiian history. The provision shapes the conversation even when it does not dictate the outcome.
How This Compares to Federal Law
Hawaii’s constitutional language stands in contrast to the default position under federal law. In DeShaney v. Winnebago County (1989), the U.S. Supreme Court held that the Due Process Clause of the Fourteenth Amendment does not create an affirmative duty for the government to protect individuals from private violence. The Court said the clause “is phrased as a limitation on the State’s power to act, not as a guarantee of certain minimal levels of safety and security.”
Under DeShaney, the government is generally not liable when a private person harms someone, even when officials knew about the danger and failed to act. The recognized exceptions are narrow: situations where the state itself created the danger, or where the victim was in state custody, such as a prisoner or a person involuntarily committed to a mental health facility.
Article IX, Section 10 does not necessarily override DeShaney in practice, because its own language grants power rather than imposing a duty. But the fact that Hawaii put the provision in its constitution at all reflects a different philosophy. Few other states have anything comparable in their constitutional text.
