Rubbish.
At 7pm the gates are locked and only the voters inside the voting station may still vote. Once they are done the IEC Presiding Officer locks the doors to the venue. The last ballot boxes are then sealed.
The IEC counting officials then remain behind in the hall, together with 2 Party Agents from each political party contesting that ward and one or teo SAPS officers. The ward candidates are allowed to be present but...
At that stage NOBODY is allowed in of out of the voting station as it has then become a counting venue.
The part agents observe the entire process but may not interfere or touch anything.
At the end of the process the party agents have to sign the result sheets or make their objections.
