Discrimination-defining in Polish legal system in the light of EU and international law

Defining 'discrimination' is crucial to proper implementation of the rule of equal treatment in practice. Both rules of non-discriminatory practices and equal treatment are strictly connected with the term of equality. Both are fundamental principles in constitutional law of most countries of the world and in international human rights protection systems. The main objective of each of this systems is to guarantee that all human beings are equally protected and have equal access to their rights. However in legislation it is hard to find clear and unequivocal general definition of discrimination. There are a lot of definitions, but most of them are fragmentary and do not recognize all aspects of the phenomena. This is the reason why authors decided to proposed one, common definition, which is derived from Polish law and Poland's international obligations.
