While evidence confirms the existence of the Phala Phala robbery and the Constitutional Court of South Africa, the provided evidence does not contain the specific text or a summary of a judgment that describes the ruling as a 'constitutional rebuke' of the ANC and Ramaphosa's use of power.

The evidence confirms the Phala Phala scandal and the existence of the Constitutional Court, but there is no specific evidence provided in the search results confirming a ruling that Parliament acted unlawfully in blocking the Section 89 impeachment process.

The evidence shows Ramaphosa addressing the media at the Union Buildings in other contexts, but there is no evidence provided that confirms he addressed the country 'in isolation' with media 'locked outside' specifically regarding the Phala Phala judgment.
