English to Spanish Law/Patents Law: Taxation & Customs Tratados

Most governments still view taxation as a central element of sovereignty and so are reluctant to accept extensive or heightened international disciplines on their taxing powers. Thus, whilst accepting supranational control/discipline over state conduct in many other areas, state parties to most modern investment treaties and instruments have either carved out taxation all together from the treaty (e.g., Art. X TAGAG Agreement on the Promotion and Protection of Investments, 1996) or restricted the applicability of some of the treaty disciplines to certain types of taxes.
