Termination clause allows either state to give diplomatic notice, ending treaty effect as tied to each state's fiscal year. The Convention permits termination by either Contracting State via written notice through diplomatic channels on or before the thirtieth of June in any calendar year after an initial five year term; termination takes effect prospectively according to each State's fiscal year commencement-January for Slovenia and April for India-and the English text is operative in case of divergence among equally authentic language texts.
