The serious doubts expressed by many, most recently Professor
Christians of McGill University, as to the Constitutional authority
cited by the US Treasury1 in support of each Inter
Governmental Agreement (an "IGA") entered into by it on
behalf of the United States government to implement FATCA have been
rendered practically irrelevant in so far as Cayman Islands legal
entities, including all companies, funds, partnerships and trusts,
are concerned by the passage, with effect from 1st July 2014, of
the enabling amendments to the relevant Cayman Islands legislation.
These extensive revisions to the Cayman Islands Tax Information
Authority Law 2014 and attendant Regulations introduce into Cayman
Islands domestic law, the provisions of the Model 1(B) IGA with the
United States (signed on 29th November 2013) and the similar (not
constitutionally doubtful) IGA signed with the United Kingdom on
5th November 2013.
