Historic title is just one of many legal instruments which may be raised by parties and used by judges to decide a territorial dispute. If a claim of historic title in given circumstances may be deemed to have been extinguished as a result of its relative weakness, the elements advanced in support of its construction, for example uti possidetis or eff ective occupation, may be used to support other types of legal claims. Taking into account its construction and its systemic conditional criteria, historic title gains maximum eff ectiveness when conditions exist which would support a fi nding of its incremental consolidation. This involves a multi-dimensional interpretation in reliance on particular elements which, taken together, create a complicated factual state in a particular territorial dispute. On the other hand, consolidation of historic title is not an argument which can be used by the indigenous native inhabitants of a territory, since their arguments are not based on claims of sovereignty.

International law reflects systemic conditions compatible with its essence, which means that a space must exist inside the borders of that order for the presence of the phenomenon of general principles. The assumption that international law is a legal system ipso facto means that general principles must exist within its borders. A general principle of law is a necessary element of every legal order. It is a form and a tool in which the efforts of the individual seeking to comprehend a given phenomenon are materialized through imposing order on it rather than by breaking it down into unconnected and independent elements. Since law is an expression of order, law therefore applies general principles. The systematicity of law, and therefore of international law as well, creates the primary source of the binding force of any norm. Considerations of natural law or positive law justifications for the presence of general principles in international law are of little consequence, as the source of general principles is the systemic nature of the law. Order and hierarchy are part of the rationalized system in which norms of law present themselves. This dependency applies also to norms of international law. The role of the judge is to fill in the appropriate normative content (general principles) in fields constituting at one and the same time both a necessary element and a consequence of the systemic character of the international legal order. Within this context the principle of good faith constitutes one of the bases for considerations concerning the extent of the international legal order. The extent of international law reaches as far as the extent to which evidence of good faith are present among the subjects of international law. The impossibility of describing relations between two states by the use of the determinants of good faith, translated in turn into a normative general principle, determinates the limits of international law.

The article features a systemic approach to digitalization in mining, covering the production process, supervision and management. Business continuity management of a critical infrastructure was characterized with respect to an industrial facility, i.e. a mine. The “SILESIA” Integrated Security System was described. This solution, offered by CNP EMAG, is an example of a systemic approach successfully implemented in industry. The article includes information about the development of technological hardware solutions as well as software which is able to assess the solutions developed in the SecLab Information Security Technology Development Laboratory in the EMAG Institute.
