In 2016, the Supreme Audit Office decided to check whether the new regulations in Polish law increased the protection of animals used for research purposesAccording to non-governmental organizations whose aim is to protect animals, retrospective assessment is not an effective form of checking experiences. Their reservations concerned the reliability of the results of the assessments carried out solely on the basis of the documentation submitted by the user in the context of the impossibility, under the provisions of the 2015 Act, to conduct inspections by local ethics committees.Publishing by local ethics committees in the Public Information Bulletin on the website of the Minister of Science and Higher Education, the so-called non-technical summaries of experiments were delayed. This is due to the lack of regulations regarding the procedure and date of their publication.Local ethics committees did not cooperate with poviat veterinarians on the exchange of information and consultations on the keeping and breeding of experimental animals in experimental units, breeding units and suppliers, and did not submit any requests for inspection.County veterinarians did not fully perform their tasks properly. After the entry into force of the 2015 law, these bodies took over from local ethics committees the obligation to conduct experiments checks. In some cases, these controls were carried out on the basis of non-binding legal status and checked the implementation of only some of the new requirements.
