Most often, a law ceases to be in effect once a new law that regulates the same area is adopted.
If it only regulates a specific situation, specific relations, or activities that are not going to be repeated, a law can cease to be in effect once it has been executed (for example, Law on Consolidation, etc.). 
A law also ceases to be in effect after the expiration of the period for which it has been adopted.
Certain provision of a law may cease to be in effect with the adoption of amendments and modifications to the law.
A law also ceases to be in effect on the basis of a decision of the Constitutional Court. In this case, only certain provisions of the law may become ineffective.
