Scholarship
Constitutionalism
For his work on transnational constitutionalism, Backer has argued that after World War II, transnational constitutionalism embraced universal human rights as the core feature that emerged with the introduction of post-conflict German and Japanese constitutions. He also has examined the emergence of theocratic constitutionalism starting from the Iranian 1979 constitution. Backer argues that constitutionalism is the legal process in which each state harmonizes with international norms and laws. Backer is well known for his works on Chinese constitutionalism. According to Backer, China is evolving towards a ":wikidata:Q11143392|single party constitutionalist state" that is grounded in its unique form of "party-state constitutionalism." Backer argued that the Chinese constitutionalist state differs from the Western model in that the CCP plays a central role in the Chinese constitutional order. In order to articulate his conception of the Chinese "single-party constitutionalist state" as a new model of constitutionalist governance, Backer delineated the history for the Chinese state-party system that began from Mao Zedong, and was subsequently improved and strengthened through the works of Deng Xiaoping, Jiang Zemin, and Hu Jintao. Backer acknowledged that Mao Zedong Thought has had a profound impact on the shaping of China's constitutionalist system, especially in regard to the idea of the Party's role as an outsider. "The CCP was not merely a vanguard party, but for a long time a revolutionary party. Even after the end of the civil war, the CCP continued to think of itself as outside the apparatus." Therefore, in terms of the relationship between the CCP and the state, there was a lengthy process of internalization where the Party as an outsider became internalized into the state through its Mass Line.
Corporate and Transnational Law
Backer has also written extensively on the imposition of binding human rights norms on multinational corporations, where "the norms internationalize and adopt an enterprise liability model as the basis for determining the scope of liability for groups of related companies. This approach... eliminates one of the greatest complaints about globalization through large webs of interconnected but legally independent corporations forming one large enterprise." Backer is also known for his work on the Sovereign Wealth Funds, where he suggested that states have deployed their private global investments as instruments for public global governance.
