The estimable Juan Cole puts the failure of the Iraqi assembly to complete the constitutional process today in clear terms:
The rule of law is no longer operating in Iraq, and no pretence of constitutional procedure is being striven for. In essence, the prime minister and president have made a sort of coup, simply disregarding the interim constitution. Given the acquiescence of parliament and the absence of a supreme court (which should have been appointed by now but was not, also unconstitutionally), there is no check or balance that could question the writ of the executive.
What the future holds for Iraq remains to be seen…
