Abstract
In this analysis piece, we consider a legal question that generated much debate in the lead-up to the US decision to withdraw from the Paris Agreement: can a Party downgrade its nationally determined contribution (NDC) to climate mitigation without running afoul of its treaty commitments? Drawing on the treaty interpretation methods set out in the Vienna Convention on the Law of Treaties, we examine the Paris Agreement’s normative framework and analyse the provision on adjustment of NDCs. We show that, while NDCs as such are not legally binding, they are subject to binding procedural requirements and to normative expectations of progression and highest possible ambition. Read together, these binding and non-binding terms make plain that a Party would contravene the spirit of the Paris Agreement if it downgraded an existing NDC. The US federal government is already scaling back its domestic climate action, such that it is unlikely to meet its NDC. Its Paris withdrawal, however, can only be formally declared in 2019 and will not take effect until 2020. We consider how, during this interim period, the legal implications of the ‘withdrawal’ approach differ from those of the ‘stay-and-downgrade’ approach.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
