The article addresses the issue of excluding the application of legal provisions to certain public-purpose investments implemented under so-called spec-acts. It fits into a broader research issue – the application of law in emergency situations. The authors focus on the omission of nature conservation regulations and the regulations governing the right to information about nature, stemming from the Act on the Construction of State Border Security, which is dictated by national security. The research objective is to verify statutory practice and practice of applying the law, which involves omitting or limiting certain fragments of the legal system for reasons of national security, the need to protect the territorial integrity of the State, or the expediting of administrative procedures or protection. The legislature’s hasty recourse to such reference clauses may lead to an abuse of law and, consequently, a restriction of civil rights.
