The paper deals with issues related to implementation of the European Council Framework Decision of 23.07.2003 (2003/577/WSiSW) on the execution in the European Union of orders freezing property or evidence in the selected Member States. The Decision is an important instrument in judicial cooperation between the EU Member States, based on the principle of mutual recognition of court orders. To begin with, the author asserts that the European Union has yet to work out a system of the execution of legal assistance in the criminal proceedings, which is specific, uniform and used by all Member States. Major critical arguments are brought forward against the functionalities of the mutual recognition principle, quoting in particular the European Arrest Warrant, considering the right to defense. Critical assessment of implementation of the Decision of 23.07.2003 is supported by the Report of the Commission of the European Communities of 22.12.2008 (COM 2008 885) and by the Communication from the Commission to the European Parliament and the Council – Proceeds of organized crime: ensuring that “crime does not pay” of 20.11.2008 (COM 2008 766). In those documents European Commission has concluded that in several Member States implementation is delayed, incomplete or not in conformity with guidelines set by the Decision. Finally, the author examines regulations of the Polish Criminal Procedure Code, the regulations introduced in Germany on 06.06.2008, amending the Act on the international judicial cooperation (not referred to in the Report of the European Commission) and the regulations of the British system of common law, which only barely implemented the Framework Decision of 2003.

The purpose of this paper is to focuse the analysis on the questions of Law occurring in the Tristan of Béroul ; more precisely, to consider the relations between the feudal pact, the honour code and the procedure of justice. The author is actually playing on several registers, a proof of his knowledge of the practice of justice in the courts of his time, the consequence of that play being an interrogation on the validity of the proof, the oath and more generally on the ambiguity of the Law.

Istotnym problemem w analizach ryzyka jest rozróżnienie pomiędzy niepewnością aleatoryczną (probabilistyczną) oraz epistemiczną (wynikającą z braku precyzji lub braku informacji). W artykule opisany został problem podejmowania decyzji inwestycyjnej w oparciu o analizę opłacalności oraz ryzyka inwestycji rzeczowej, w sytuacji gdy część parametrów wejściowych modelu decyzyjnego przedstawiona jest rozkładami prawdopodobieństwa, a część rozkładami możliwości, innymi słowy w sytuacji występowania danych hybrydowych. Analiza ryzyka dla tak zdefiniowanego problemu została wykonana za pomocą metody łączącej symulację Monte Carlo z metodą wykonywania operacji arytmetycznych na zależnych liczbach rozmytych. W artykule do realizacji tych ostatnich wykorzystano metodę programowania nieliniowego. W wyniku tego typu obliczeń uzyskano rozmytą zmienną losową, której interpretacja może być trudna dla praktyków życia gospodarczego. Na podstawie krytycznego przeglądu istniejących mierników ryzyka definiowanych w sytuacji wykorzystania hybrydowych danych, zaproponowano nową metodę podejmowania decyzji inwestycyjnej. W części praktycznej przedstawiono proces podejmowania decyzji inwestycyjnej na przykładzie inwestycji rzeczowej w sektorze hutniczym.

In risk analysis it is very important to distinguish between aleatory (probabilistic) and epistemic (due to lack of precision or information) uncertainty. In this paper is described a problem of making an investment decision on the basis of the analysis of effectiveness and risk of a tangible investment, in a situation when some model parameters are described by probability distributions and some are described by possibility distributions, i.e., in the presence of hybrid data. An analysis of risk for such defined problem was performed using a method which combines Monte-Carlo simulation with the method for performing operations on dependent fuzzy numbers. Those operations were realized using the nonlinear programming. As a result, a random fuzzy variable was obtained, which is difficult to be interpreted for practitioners of economic life. On the basis of critical review of the existing risk measures defined in the case of hybrid data, a method for making an investment decision was proposed. The practical part of the paper presents an investment decision making process on the example of a tangible investment in metallurgical sector.
