The Office of the United States Trade Representative challenges the notion that ISDS challenges "the sovereign ability of governments impose any measure they wish to protect labor rights, the environment, or other issues of public welfare". The International Bar Association (IBA) mirrors these sentiments, noting that "while investment treaties limit states’ ability to inflict arbitrary or discriminatory treatment, they do not limit (and, in fact, expressly safeguard) a state's sovereign right to regulate in the public interest in a fair, reasonable, and non-discriminatory manner." The White House notes that investment protections are a component of more than 3,000 trade agreements, the vast majority of which have some form of neutral arbitration. The United States is party to at least 50 such agreements, has only faced 13 ISDS cases and never lost an ISDS case. The White House asserts that the ISDS components of the TPP are an upgrade and improvement on ISDS in other trade agreements: TPP makes it absolutely clear that governments can regulate in the public interest (including with regard to health, safety and the environment); TPP includes the ability to dismiss frivolous claims quickly and award fees against the claimant to deter such suits; sham corporations will be prevented from accessing the investment protections; and arbitration proceedings under TPP will be open to the public and allow for inputs from non-parties.
