As the title suggests the article deals with certain quantitative analysis of legislation, the backbone of any legal order, using methodological and theoretical approach, as well as investigative and analytical approach applied, in this case, on legislation, i.e. the legal order of the Czech Republic. It can be characterized as a specific statistical method based on the quantification of investigated phenomena of interest. However, this quantification cannot be done in a standard way – mainly because in legal theory any attempt to approach the investigated topics with quantitative exactness is a rare effort, there are no standards and sometimes such attempts may even be met with suspicion. The introduction is therefore necessarily focusing on the question whether such legal phenomenon as legislation can be described quantitatively. The next part is dedicated to the methodology and clarification of author’s approach, i.e. mainly definitions and interpretations of the introduced and monitored variables and their operationalization. The third part of the study is an application of the introduced methodology on concrete research: quantitative description of Czech legislation over the last 12-month period, for which full data set has been collected. Thanks to regular quantitative monitoring of Czech legislation, and other similarly focused research efforts, in recent years we are able to compare the results of these analyses for different periods. The key variables and quantitative indicators were derived from the formal structure of legislative documents with emphasis on the relevance of the law, branch structure of legislation and also on the international factor in this context. Changes documenting the development of legislation are then highlighted within this framework. This procedure could be an inspiration for similar quantitatively and thematically oriented comparative research efforts in different countries, especially when it comes to the growing cooperation between Central European countries.
