Concept:Transparency and accountability in governance are best secured when those in power are bound by the constitution and the rule of law.
Explanation:Constitutionalism means that every government action must follow the constitution and existing laws.
This creates a framework of checks and balances, so leaders cannot act arbitrarily or hide their decisions.
When public officers respect constitutional limits, their actions become open to scrutiny and answerable to the citizens.
Accountability is thus strengthened, because any abuse of power can be challenged legally.
In contrast, supervising the judiciary would weaken an independent check on the government.

Holding trials in secret would hide injustices and reduce public trust.
Therefore, ensuring constitutionalism thrives is the direct way to promote transparency and accountability.
