The Principle of Legal Certainty and Government Interventions in the Economy %K Legal certainty %K economic public law %K legitimate expectation %K administrative decisions %K Predictability %R 10.22059/jplsq.2017.63099 %X In my opinion, the necessity of government’s intervention in economy is beyond doubt, but if such intervention become incompatible with the rules, it would cause negative effects on the market system. One of the principles that is needed to be observed in such intervention is the principle of legal certainty. This principle represent predictability and reliability of administrative decisions. So citizens would be able to trust the government institutions and plan for their lives. The Elements of the legal certainty are as follows: legitimate expectation, non- retroactivity of administrative decisions, introducing the law publicly in reasonable and transparency. Some of these indices has been recognized in the Iranian legal system by the legislator or judicial authorities .But in many cases this principle is not being observed. However, due to its impact on the economy it is necessary to pay due attention to this principle. %U https://jplsq.ut.ac.ir/article_63099_1f0d655ff393782fd8d0a09376235a28.pdf
