The development of the modern Slovenian Health Law was first urged by the adoption of a new Constitution in the year 1991. Since then the Jurisprudence of the Constitutional Court has played a noticeable role by assuring the effective protection of Human Rights in the field of Health Law Legislation, which includes about thirty statutes. In several cases the Constitutional Court had to annul some parts of Health Legislation because they were not in accordance with the Constitution. The constitutional review of the Constitutional Court has been a very important factor in building and improving the Slovenian Health Law. Its jurisprudence can be regarded as one of the main causes for a comprehensive Health Law Reform which started in the year 2006.
