The Court can either act, or encourage Congress to exercise its Article IV Section 1 powers to control the manner in which the records are shared. Note that Congress cannot prevent Arizona from its full faith and credit access to Hawaii's public records, it can only direct the manner in which those records may be proved.
Either way, via SCOTUS or Congress, the matter must be discussed. There are no questions of standing in this matter between the states, SCOTUS, and Congress when demanding Article IV Section 1 access to Hawaii's records.

You mean the same Supreme Court that just upheld Obama's abhorrent healthcare scheme?
Pffft!
