The Gauteng ANC on Friday said disciplinary action against 19 of its members in Heidelberg, some of them councillors, should happen by the end of May.
The party suspended them earlier this week after receiving reports that they were involved in violent protests, which saw several government properties torched in Ratanda earlier in 2012.
The township exploded in March when disgruntled residents went on a rampage over high electricity tariffs and power cuts.
The ANC's Dumisa Ntuli said, "The presiding officer has not set a date yet but we expect the hearing to take place in the next coming few days."
Most of the service delivery protests, throughout, the country have been marred by violence.
In Mpumalanga, residents who were protesting for water damaged municipal property.
Earlier in May, Sir Lowry’s Pass Village residents protested over poor service delivery.
The protest turned violent and the protesters threw a petrol bomb inside a local police station.
Meanwhile, Minister of Co-operative Governance and Traditional Affairs Richard Baloyi expressed his concern with the violent service delivery protests.
The minister said political agendas were behind some violent service delivery protest, but he also said in some cases the complaints were genuine.
