A group of South Sudanese lawyers filed a case to the country's top court on Monday challenging the president's postponement of elections and extension of the transitional government's term for two years.

The government in South Sudan has postponed elections scheduled for December for two years citing the need to complete processes such as a census, the drafting of a permanent constitution and registration of political parties.

South Sudan postponed elections that were due in December for two years, extending the mandate of the nation’s transition government.

International guarantors of South Sudan's peace process said the transitional government's postponement of elections due in December was disappointing and showed its failure to implement a 2018 peace plan.

President Cyril Ramaphosa says South Africa will continue to support South Sudan following a decision to extend the transitional period agreed in a peace deal.
