been fixed, a single compound fine shall be imposed under point 4 of paragraph 2 of the this Article. Continued Criminal Offence Article 54 (1) Any person who commits or attempts to commit simultaneously or successively two or more equal, or of the same type, criminal offences against property out of greed or to cause damage, which with regard to the place, method and other equal circumstances represent a uniform activity, shall commit a continued criminal offence. (2) The provisions on concurrence under the preceding Article of this Penal Code shall not be applied for the continued criminal offence, but a combined sentence within the limits of the sentence, prescribed for the gravest criminal offence, shall be imposed for all criminal offences together, whereby in addition to the principal sentence of imprisonment a mandatory accessory sentence in the form of a fine shall be imposed as well. (3) The perpetrator, who gains major property benefits or causes major or great loss of property under paragraph 1 of this Article, because of which a severer sentence is prescribed for the criminal offence, shall be imposed this severer sentence under paragraph 2 of this Article, if he wanted to gain such property benefits or cause such damage with simultaneously or successively committed criminal offences. Sentencing of Convicted Person Article 55 (1) In the event of a perpetrator being tried for a criminal offence committed either prior to the commencement of or during the serving of an earlier sentence, a combined sentence shall be imposed on him for all criminal offences pursuant to Article 53; the court shall take into account the fact that his former sentences have already been fixed. The sentence or part of it, which the convicted person has already served, shall be counted as part of the sentence imposed. (2) For a criminal offence committed during the period of the serving of a sentence in prison, the perpetrator shall be sentenced irrespective of earlier sentences if the application of provisions under Article 53 would lead to an unreasonably short term left to be served. (3) A disciplinary sanction shall be imposed on a convicted person who during the period of his serving a sentence in prison committed a criminal offence, for which a fine or imprisonment for a term not exceeding one year is prescribed by the statute.
