Abstract
This presentation tends to outline the issue of evidence with regard to Computer crimes (mostly based on Articles 218, 236a and 241 of the Criminal Procedurę Codę). It allows to State that the recent amendments to these provisions, adopted in January 2003, will probably tum out to be insufficient. The need to included further regulations conceming these pieces of evidence into the Polish criminal procedurę law comes not only from the development of Computer Sciences and arising new forms of Computer crimes, but also from the necessity of adjustment of the Polish law to European standards in this respect.
