The Cape Town Magistrate's Court will on Tuesday hear the assault case against EFF MP Marshall Dlamini.
Dlamini was caught on video slapping a plainclothes police officer after the State of the Nation Address (SONA) in February.
Police spokesperson Brigadier Vishnu Naidoo confirmed in February that two charges of assault had been laid by a female sergeant and a male warrant officer.

Naidoo had said that police were investigating the matters and would send the case to the Director of Public Prosecutions for a decision on whether or not to prosecute.
Following the slapping incident, the EFF claimed that the altercation was in response to a threat against the life of their leader, Julius Malema.
"The EFF has received media enquiries regarding an assassination threat on the life of the CIC (commander-in-chief) Julius Malema, which had been planned to be executed during the 2019 State of the Nation Address yesterday," read a statement by EFF spokesperson Mbuyiseni Ndlozi at the time.
"The security threat implicates elite members of the police, who are in collaboration with right-wing groups to take the life of the CIC, in an attempt to undermine the advances on the expropriation of land without compensation discourse, that will soon be law."
