The workshop took place while Commonwealth Deputy Secretary-General Mmasekgoa Masire-Mwamba was on a visit to the island nation to review arrangements for the next Commonwealth Heads of Government Meeting (CHOGM), set to take place in Colombo in November.
Prominent Commonwealth nations like Canada and Australia have objected to hold the summit in Colombo due to the countries human rights record, but the 54-nation grouping has decided to go ahead with its plans.
"The workshop had been very comprehensive in building their knowledge on human rights issues and he was pleased with the attendance at the workshop," Priyantha Perera, a retired judge and SLHRC chief said.
Global rights group, such as Human Rights Watch (HRW) alleges Sri Lanka has taken no meaningful steps to address serious abuses by government forces in the last stages of the conflict against the LTTE in 2009.
Since 2009, Sri Lankan government has been responsible for a worsening human rights situation that includes clampdowns on basic freedoms, threats and attacks against civil society and actions against the judiciary and other institutions imperilling Sri Lanka's democracy, HRW said in a recent report.
