Opposition lawmakers are heaping criticism on South African President Jacob Zuma after a court said he violated the constitution, but the institution that can oust him — the ruling African National Congress party — has yet to turn on its leader.

The main opposition party, the Democratic Alliance, said Friday that it will push to impeach Zuma after the Constitutional Court ruled that Zuma "failed to uphold" the constitution when he didn't pay back some of the millions of dollars in state funds used to upgrade his private home.

Impeachment requires a two-thirds majority in a vote in parliament where the ANC party has a comfortable majority. The top court also ruled Thursday that parliament had failed in its obligations by not holding Zuma to account in the spending scandal.
