There has been much discussion in recent years – and in recent weeks on this blog – of the potential for investment treaty arbitration to benefit from a ‘comparative public law’ approach. In brief, the approach conceives of investment treaty arbitration as a form of public law, and calls for tribunals to draw on comparative domestic constitutional and administrative law, as well as other regimes of international public law such as WTO law and human rights law, to give content to the often vaguely-worded standards of typical investment treaties.
In the midst of contemporary enthusiasm for comparative public law, it is tempting to think that the approach is a new one that has been growing in prominence only over the last few years. However, this week brings news from Investment Arbitration Reporter that an UNCITRAL-rules investment treaty award dating from 1995, Saar Papier Vertriebs GmbH v Poland, has been unearthed. Amongst other aspects detailed by IAReporter, the case is particularly notable for its explicit use of domestic administrative law to interpret the provisions on indirect expropriation in the Germany-Poland BIT.
Indeed, this newly-uncovered investment treaty award – only the second ever (currently) known to be rendered, following AAPL v Sri Lanka in 1990 – contains intriguing indications that the comparative public law approach is a practically useful one for investment treaty arbitration. Furthermore, the age of this award raises the tempting view that, rather than being a new development in the field, comparative public law has been there all along.
However, as I discuss below, despite the treaty context of the claim, it is unclear whether the Saar Papier tribunal considered itself to be applying international law. Without this international law framework, it becomes more difficult to characterise the case as an instance of comparative public law at work. Read the rest of this entry…
