Questão jurídica principal
Whether the IRS request met the treaty requirements for administrative assistance.
Decisão extraída
The request was sufficiently concrete and met the treaty-based requirements for assistance.
Fundamentação extraída
It identified the persons under investigation, tax type, years, the suspected Swiss entity and the requested categories of documents; the fact that some details about the entity were uncertain did not bar assistance because the request sought to clarify those very points.
