Notwithstanding the above a number of judges have opined that the denial of ALL petitions issued pursuant to the Information Quality Act are not judicially reviewable. The underlying reason, not written but muttered, is that the Congress could not have meant the Act to provide entry to the courts by such a large number of potential plaintiffs.
