Durban - Cope has vowed to boycott proceedings in the National Assembly after the ANC in Parliament refused to take action against President Jacob Zuma following the Constitutional Court ruling.FULL TEXT: Cope withdraws from parliamentary activitesSpokesperson Dennis Bloem said the party's executive committee had considered the judgment, which was handed down two weeks ago."The executive committee noted that the refusal of the ruling party in Parliament to act against the incumbent in the office of the president made it guilty of contempt of court," he said."It was therefore resolved not to allow any Cope representative in the National Assembly to take part in its proceedings until there is clarity from the Constitutional Court on how to proceed."Cope is determined not to make itself guilty through participation in activities that are in contempt of court. Our representatives cannot break their oath of office," Bloem added. He said that the party would approach the Constitutional Court to "seek clarity on the way forward".The Constitutional Court found that Zuma had failed to uphold the Constitution when he did not comply with Public Protector Thuli Madonsela's remedial action regarding payment for the upgrades to his Nkandla homestead.It also ruled that the National Assembly had failed to uphold the Constitution when it set aside Madonsela's report.
