agrees "that secrecy has gone too far" in many ISDS cases, but notes that "TPP negotiators heeded this criticism" and opened up ISDS cases to greater transparency. According to the International Bar Association (IBA), states have won a higher percentage of ISDS cases than investors, and that around one-third of all cases end in settlement. Claimant investors, when successful, recover on average less than half of the amounts claimed. IBA notes that "only 8 per cent of ISDS proceedings are commenced by very large multinational corporations." IBA challenges the notion that ISDS is biased against developing countries, noting that there is "no correlation between the success rates of claims against states and their income levels or development status." IBA notes that ISDS is necessary even in countries with sophisticated domestic legal systems because those domestic courts rule according to domestic laws, not international law. IBA notes that "increasingly, awards require the losing party to pay arbitration costs and legal fees to the winning party", which deters investors from initiating unmeritorious cases.

The USTR insists that if countries like Malaysia and Vietnam do not enforce provisions relating to forced labor, human trafficking and collective bargaining, they will cease to get the economic benefits of the TPP agreement. The Peterson Institute for International Economics asserts that "the TPP includes more protections of labor rights than any previous US free trade agreement." In January 2016, Human Rights Watch said that the TPP side agreements with Vietnam, Malaysia, and Brunei "are a unique and significant step in efforts to protect labor rights in trade agreements" but noted that enforcement of these rules remains to be seen: "gauging compliance will require subjective assessments by the US that may take years to carry out and face obstacles arising from foreign policy objectives, commercial interests, and other political considerations." Dartmouth economics Professor Emily J. Blanchard argues that while the TPP has been roundly criticized on the political left, progressives should actually be supportive of the TPP: "The TPP’s promise of a new
