This paper explores the reliability of extradition treaties as objective tools for assessing human rights conditions, using the China-Australia extradition treaty as a case study. Unlike biased statements from government officials, extradition treaties are formal legal agreements, offering a more credible lens for evaluating justice systems. The paper examines Australia's refusal to ratify the 2007 treaty with China, citing concerns about torture, politically motivated charges, and the death penalty. It also highlights some complexities in China's legal system, including the shuanggui practice and high conviction rates, raising questions about procedural fairness. Australia’s decision to resist ratification underscores its commitment to human rights and sets a precedent for other nations in handling diplomatic relations with China.
