The doctrine was formalized in a 1927 treatise by Alexander Nahum Sack, a Russian émigré legal theorist, based upon 19th Century precedents including Mexico's repudiation of debts incurred by Emperor Maximilian's regime, and the denial by the United States of Cuban liability for debts incurred by the Spanish colonial regime. According to Sack:
"When a despotic regime contracts a debt, not for the needs or in the interests of the state, but rather to strengthen itself, to suppress a popular insurrection, etc, this debt is odious for the people of the entire state. This debt does not bind the nation; it is a debt of the regime, a personal debt contracted by the ruler, and consequently it falls with the demise of the regime. The reason why these odious debts cannot attach to the territory of the state is that they do not fulfill one of the conditions determining the lawfulness of State debts, namely that State debts must be incurred, and the proceeds used, for the needs and in the interests of the State. Odious debts, contracted and utilised for purposes which, to the lenders' knowledge, are contrary to the needs and the interests of the nation, are not binding on the nation – when it succeeds in overthrowing the government that contracted them – unless the debt is within the limits of real advantages that these debts might have afforded. The lenders have committed a hostile act against the people, they cannot expect a nation which has freed itself of a despotic regime to assume these odious debts, which are the personal debts of the ruler."
Patricia Adams, executive director of Probe International (an environmental and public policy advocacy organisation in Canada), and author of Odious Debts: Loose Lending, Corruption, and the Third World's Environmental Legacy, has stated that:
by giving creditors an incentive to lend only for purposes that are transparent and of public benefit, future tyrants will lose their ability to finance their armies, and thus the war on terror and the cause of world peace will be better served.
A recent article by economists Seema Jayachandran and Michael Kremer has renewed interest in this topic. They propose that the idea can be used to create a new type of economic sanction to block further borrowing by dictators.
