Commission responded to social issues in an efficient manner. There were a total of 6,946 complaints regarding human rights violations, which was more than in 2011 (5,424 cases). The Commission resolved 6,936 cases, which is the largest number recorded since its establishment. By entity, the largest number of complaints were filed in the order of: institutional group care facilities (2,115or 30.4%), correctional facilities (1,731 or 25.0%), and the police (1,222 or 17.6%). Also, the number of complaints for school violence, which was one of the hottest social issues in 2012, jumped 3.3 fold from the 34 of 2011 to the 113 of 2002.

These days, however, an increasing number of complaints are resulting from the conflicts of various rights and interests, and consequently, complaints are also becoming more complex and complicated. Complaints of human rights violations that result from structural and institutional elements are on the rise as well. In 2012, the Commission received a total of 2,548 complaints with regard to discriminatory acts, which was a 744 case increase compared to the previous year, and resolved 2,560 cases. One of the causes for this increase can be found in the increased number of discriminatory acts that were detected according to the Disability Anti-Discrimination Act, whose enactment widened the scope of coverage. Discrimination based on academic background, place of origin or country of origin was slightly less than the previous year, but on the contrary, discrimination on the grounds of social status, medical history, sexual orientation and appearance, and sexual harassment increased to a certain degree. Discrimination against people with disabilities accounts for 52% of all discrimination cases.
