The article concerns the criminal policy of courts in cases concerning offenses against the family and guardianship in 2008–2018. The study presents the results of the analysis of statistical data illustrating the judicial tendencies of criminal courts in cases of offenses specified in Chapter XXVI of the Penal Code. The text tries to answer the question: did the changes in criminal law that took place in 2015 and 2017 influenced to some extent the jurisprudence on crime against the family and care? In the article, the amendments from these two years were analyzed with particular attention, as one of them was essential for the entire criminal law system in Poland, while the other was extremely important, especially in the context of crimes harming
the welfare of the family and care.

Legislative response to tax crime reflects the trends that are observed throughout criminal law resulting from theory to which, a crime is an evidence of a defectively constructed law, the result of which is increasing instability, casuistry and regulatory drift with tendency to extend of scope criminalization and aggravating penalties. 
In the field of tax crime, it is called “closing tax loophole”.
The legislator, by declarating war on tax frauds, didn’t increase penalties for tax frauds, however, legislator increased penalties for unreliable invoice and bills trading. Within the Fiscal Penal Code, this is reflected by tightening of a provisions concerning the unreliable invoice and bills trading, while within the Criminal Code – introducing a aggravated types of documents forgery which have their subject invoices.
The draft amendment of the Fiscal Penal Code (December 2018) was another manifestation of discussed tendencies. Its essence came down to further extend of scope criminalization, aggravating penalties and distortion of priority of principle for enforcement to public levies.
However, this draft didn’t enter into force, instead, for two years – the legislator, by means of amendments, consequently, extends the scope of criminalization, extending it to the cases of failure or improper performance of information obligations.
Apart from tax frauds, what concerns to tax authorities and legislators of several countries, is the so-called “aggressive tax optimization”, in which certain activities, e.g., asset disposal or social structure transformation, are undertaken solely or primarily – tax burden reductions. Its criminalization extends to the far “frontiers” and leads to imposition of criminal penalties for failure or improper fulfillment of reporting obligations the so-called “tax scheme”, which is intended to allow, to tax authorities – an early identification of taxpayer’s behaviours that are reflected by aggressive tax optimization.

In the interpretation of criminal law, an important role is played by the presumption of the common (general, colloquial) meaning of statutory expressions. Determining the common meaning in the process of applying the law is usually based on the linguistic intuition of the procedural authority or on dictionaries. In the article, we present an alternative source
of knowledge about the common meaning of linguistic corpora. The use of corpora as a tool of legal interpretation has been intensively discussed in American literature for several years. The main objections are raised in the context of criminal law. The article reviews the main arguments raised in the American debate and relates them to Polish legal culture. Moreover, some exemplary corpus analyzes in criminal cases are presented, both in the context of legal interpretation and the assessment of linguistic elements of the facts of the case.

Corruption is one of the most dangerous phenomena of contemporary society. So it is no wonder that the legislator and the whole society are always looking for new ways to effectively combat such negative phenomena. However, corruption has one specific feature, which is high latency, compared to other forms of crime. Given that corruption is characterized by a high degree of latency, it is understandable that traditional means of criminal law are unable to ensure effective detection and prosecution of this type of crime. There is a relatively new procedural legal instrument in the fight against corruption in Section 159c and 159d of the Criminal Procedure Code. However, the question is whether this new provision is not merely a covert introduction of the institution of the crown witness into the Czech legal order.

One of the basic measures to prevent the spread of many infectious diseases is to distance oneself from other people. It is therefore no coincidence that in the time of the COVID-19 pandemic, the Polish legislator has resorted to such solutions as home isolation of patients, quarantine of people who have come into contact with the infected, and restrictions on the activities of institutions gathering many people. Similar methods were used in other countries. One of the more dramatic side effects of the ban on leaving home is the exposure of isolated people to violence in the household. The simultaneous suspension of the activity of aid institutions makes it much more difficult for the victim to obtain support. The text deals with the problem of legal and factual measures to counteract domestic violence in conditions of separation. The authors
analyze Polish legal regulations, both those introduced for the purpose of counteracting domestic violence and those specifically, related to combating the virus. They are looking for answers to the question of what measures are effective in combating domestic violence in the extreme time of the pandemic. They recognize, however, that the experiences from this period can increase the level of protection of victims of violence at all times.
