This Note makes two assertions. First, despite the fact that the Codex guidelines do not specifically invoke the Precautionary Principle in name, it can indeed be read into the guidelines in the amount of deference given to states in how they assess risk. This in turn means that the E.C.'s Deliberate Release Directive should be enjoy a presumption of compliance with both the SPS Agreement and the GATT. The second assertion is that even if the adjudicating body of the WTO finds that the Deliberate Release Directive, in relying on the Precautionary Principle, prescribes a higher level of protection than the Codex guidelines allow for, it still complies with the SPS Agreement and the GATT in its own right.
