The former judge, relieved of his duties after 4 months of service, appeared on 17 and 24 October, according to the League for Human Rights in the Great Lakes Region (LDGL), a collective based in Kigali.
Mulihano, who has pleaded not guilty, is accused of having buried alive Innocent Nkubana, who had been seriously wounded by Interahamwe militiamen, writes the LDGL on its Internet site.
The defendant affirms not to have taken part in the burial of Nkubana, but confirms that the victim was indeed buried alive.
Among the witnesses for the prosecution is François Nkurunziza, sentenced to 30 years in prison, while Marciana Nyirambeba, the mother of the victim, is testifying for the defence, specifies the LGDL.
The trial will restart Wednesday, adds the organization.
Inspired by ancestral village assemblies where wisemen would settle disagreements while sitting on the grass (gacaca, in Rwandan language), the semi-traditional gacaca courts are charged with trying the majority of the people accused of having played a part in the 1994 genocide.
They are presided not by professional magistrates but by "people with integrity" elected amongst the community.
They can sentence defendants up to life in prison.
The executive secretary of the national service of the gacaca courts (SNJG), Domitille Mukantaganzwa, hopes that these courts will have completed their work by the end of the year.
