Article 7(2) of the Charter. The Respondent also adds that, if the Applicants are complaining of the length of penalty for armed robbery, the Court does not have the authority to examine the constitutionality of the length of a punishment stipulated for a crime in its domestic legislation. iii) The Court's Assessment 98. The Court observes from the particulars of the case, that with regard to the length of the imprisonment imposed on them, the Applicants simply assert that their sentence to 30 years imprisonment violates the Constitution of the Respondent and Article 7 (2) of the Charter. Article 7 (2) of the Charter provides that: "No one may be condemned for an act of omission, which did not constitute a legally punishable offence at the time it was committed. No penalty may be inflicted for an offence for which no provision was made at the time it was committed. Punishment is personal and can be imposed only on the offender." 99.lt emerges from the file that the relevant question at stake is whether the penalty to which the Applicants were sentenced on 19 December 2005 and upheld on 24 December 2009 was not provided for in the law. 100. The records before this Court indicate that the armed robbery for which the Applicants were convicted was committed on 5th of November 2002. Following their extradition to the Respondent on 24 March 2003, the Applicants were charged at the Resident Magistrate's Court of Dar es Salaam at Kisutu for crimes of armed robbery and conspiracy to commit crimes contrary to Sections 285 and 286 of the Penal Code as amended by Act No. 10 of 1989. Both crimes were defined in the Penal Code and the amending Act. According to Section 286 of this Penal Code a person convicted of armed robbery is liable to a penalty of life imprisonment with or without corporeal punishment. Section 5 (b) of the Minimum Sentences Act of 1972 as amended by the 1994 Written Laws Amendment, also prescribes that the minimum sentence for the said offence is thirty (30) years. The two provisions read together show that the applicable penalty for armed robbery is a minimum of thirty (30) years imprisonment. 27
