The chant "Pay back the money" filtered into South Africa's highest court on Tuesday, as judges heard a case in which President Jacob Zuma is accused of violating the constitution in a scandal over state spending on his private home.
 
Inside court, lawyers argued before 11 judges over whether the president broke the law by failing to follow a 2014 recommendation from the state watchdog agency that he pay back some of the more than $20 million in security upgrades to his rural home.

Outside, several thousand opposition party supporters demonstrated against what they described as corruption by the head of state, shouting that he should return state money used to improve his private home.

Zuma's office, on Feb. 3, said he was willing to reimburse some money, an about-turn to his previous position that he did nothing wrong. His critics said he was trying to avoid the embarrassment of a court hearing and a repeat of last year's heckling during his State of the Nation address, to be held on Thursday.
