The article critically evaluates the special regulation of the review of binding opinions issued for the purpose of proceedings under the Building Act, which as of 1 January 2018 was newly introduced by an amendment to Building Act No. 225/2017 Coll. and which substantially limits the possibility of review of the binding opinions. Special attention is paid to the issue of guarantees of protection of public interests, to the preservation of legal means of protection of legality in proceedings before public authorities and to the principle of equality of persons with which the amendment is, according to the opinion of the author, in conflict.
