The court ruled late on Monday that the law adopted by the parliament in March 2014 to completely close down the centers, known as dershanes in Turkish, as of September 1, 2015, was unconstitutional.
The measure to annul the legislation was adopted following a petition by Turkey's main opposition Republican People's Party (CHP).
The dershanes are very popular in Turkey. A total of 3,800 of these centers are catering for 1.2 million students, who are seeking to win a place in top schools and most sought-after universities.
Opponents of the law argued that the legislation would exclude the most underprivileged students from top academic centers, and augment the impact of socio-economic differences on the results of entrance examinations.
The critics further noted that the law was contrary to Turkey’s Constitution, including Article 17, which says that "everyone has the right to the protection and development of tangible and intangible assets.”
The Justice and Development Party (AK Party) government, in a surprise move, decided in November 2013 to close dershanes as part of educational reforms. The AK Party government's bill engineered by then Prime Minister and now President Recep Tayyip Erdogan was passed by the parliament on March 7, 2014 and signed into law by then President Abdullah Gul five days later.
