4.  The applicant was born in 1974 and lived in the Sverdlovsk Region. 5.  On 6 April 2012 the Leninskiy District Court in Nizhniy Tagil issued a detention order in respect of the applicant who had been charged with murder and had absconded. The order was to be valid for an initial period of two months following the applicant’s arrest. 6.  On 19 February 2013 the applicant was apprehended in China and extradited to Russia. 7.  On 30 April 2013 the Leninskiy district prosecutor asked the District Court to extend the applicant’s detention for a further two months. On the same day the District Court granted the application in part. It extended the authorised period of detention “for one month, until 19 May”. 8.  The applicant filed an appeal. He complained, in particular, that the initial two-month detention period had expired already on 19 April 2013 and that his subsequent detention had been unlawful. 9.  On 10 June 2013 the Sverdlovsk Regional Court rejected the appeal. On 26 September 2013 a judge of the Regional Court refused the applicant leave to appeal to the regional cassation instance. 10.  On 4 March 2014 a judge of the Supreme Court of the Russian Federation refused the applicant leave to appeal to the Supreme Court. The judge noted, in particular, that the belated filing of an application for an extension of the authorised period of detention was not a ground for varying the custodial measure.
