From the Australia-Korea FTA:
ARTICLE 20.5: RULES OF INTERPRETATION
... Where an obligation under this Agreement is identical or substantially identical to an obligation under the WTO Agreement, the panel shall adopt an interpretation which is consistent with any relevant interpretation established in rulings of the DSB. ...
So what happens if there are two panel rulings, but no AB rulings, and the panel rulings are not entirely consistent?
Or what if there has been a dissent? The provision says "any relevant interpretation." Could there be multiple relevant interpretations?
