With permission, I have now posted on SSRN my paper on the Treasury White Paper and the EU state aid cases, which appeared in Tax Notes and Tax Notes International on September 19 of this year. It's available here.
UPDATE: The piece was temporarily taken down by SSRN, because it requires permission from Tax Notes, which I have. I've communicated this (with relevant proof) to SSRN, and I am hoping it will be back up soon.
FURTHER UPDATE: Ah, we're back in business. I thnk it's the same link as previously, but just to be sure, use this.
