A bit of a heavy-handed title however I am often reminded of this maxim, credited (perhaps incorrectly) to Benjamin Disraeli KG. Over at SSRN I refer to it in discussing the statistical merits of the proposed Common European Sales Law. Over and above the (lack of) justification for the proposal, its relationship with European Private International Law is very unclear. The European Commission marches on with its harmonisation of European conflicts law however I for one would argue that with the proposed CESL it may have hit the proverbial wall.
