Financial sanctions may be increased if the perpetrator fails to pay a fine and fails to restore the situation to its previous state (in which case the authority may double the fine) or the same administrative offence is repeated within two years (in which case the fine may be increased to the upper limit). Withdrawals of a permit or bans on the performance of a particular activity as a result of administrative offence are used sporadically. The code recognises eight kinds of crimes against the environment, including jeopardising and damaging the environment, unauthorised handling of waste, and poaching. Natural persons (individuals) and legal persons (companies) have been liable for administrative offences, but until 2005 only natural persons could be held liable for criminal offences.
