In February 2016,
United Nations' human rights expert
Alfred de Zayasargued that the TPP was fundamentally flawed and was based on an outdated model of trade pacts, and that governments should not sign or ratify the TPP.
[184][185] According to de Zayas, the international human rights regime imposes binding legal obligations on countries, including the
International Covenant on Civil and Political Rightsand the
International Covenant on Economic, Social and Cultural Rights, and trade must be done under the human rights regime. Under the ISDS in the TPP, investors can sue a government, while a government cannot sue investors. De Zayas argued that this asymmetry made the system unfair. He added that international law, including accountability and transparency, must prevail over trade pacts.
