Can the validity of anything done by the President in his discretion be called into question in any court?

The correct answer is No. This question pertains to the constitutional immunity granted to the President regarding actions taken in their discretion. According to constitutional provisions, particularly in many parliamentary systems, the President enjoys certain immunities to ensure the smooth functioning of the executive and to protect the office from frivolous litigation. Actions performed by the President in their discretionary capacity are generally not subject to judicial review.

• A: Yes is incorrect because it contradicts the principle of presidential immunity for discretionary acts.
• C: Only in the Supreme Court and D: Only in the High Court are incorrect as they still imply judicial review, which is not applicable for discretionary presidential acts.
