Under the OBT agreement, the compliance assessment states that: Appendix 1.1 specifies that “product characteristics or their associated production processes and methods” are subject to technical rules, meaning that it does not apply to the PNPRP. However, in Appendix 1.1 and 1.2, the second sentence, the word “linked” is omitted, indicating that technical requirements may apply to labelling. Some academics argue that the second sentence is read in the context of the first sentence and should therefore be tightened.  The CTA ensures that technical regulations, standards, testing and certification procedures do not create unnecessary trade barriers. The agreement prohibits technical requirements that are created to restrict trade, contrary to technical requirements created for legitimate purposes, such as consumer or environmental protection.  Its objective is to avoid unnecessary barriers to international trade and to recognize all WTO members in order to protect legitimate interests on the basis of their regulatory autonomy, although they encourage the application of international standards. The list of legitimate interests that may justify a trade restriction is not exhaustive and covers the protection of the environment, health and safety of people and animals.
