The way day-fines are fixed in the Czech Republic is unclear. In order to propose changes of the Czech system, all European countries using day-fines are compared and analysed. Three main areas are then particularly discussed: The fixing of the amount of one day fine, of the number of day fines and of the number of days of imprisonment in case of default. The article closes with discussion about different approaches which might change the current practise. A way which might be used by the Supreme prosecutor‘s Office is considered to be the most suitable one.
