Although the means to apply the mechanism of unpredictability is nowadays one of the most debated subjects in civil law, it is almost impossible not to be tackled in other domains, such as public law. Whereas the theory of contractual unpredictability had been born under the constraints of administrative jurisdiction, it became a lot more popular after its regulation in the Romanian Civil Code. There were numerous reasons to undertake this measure. After the financial crisis of 2008-2009, an institution that could balance the inequity between the parties’ rights and obligations – torn by an exceptional change of the circumstances – was demanded by many people who concluded different types of credit loans. The situation was new, but somehow foreseen. From the perspective of public law, even though there were few specific regulations, the jurisprudence elaborated some theories regarding the means of the harmonisation of economic and judicial realities.
