Unconstrained authorities can severely undermine civil liberties by granting excessive power without adequate checks and balances. Such authorities often pursue policies that infringe on individual rights, such as freedom of speech, assembly, and privacy. In instances where governance lacks accountability, citizens may face repression and intimidation for voicing dissent or challenging the regime. This can create a culture of fear, stifling public discourse and leading to human rights abuses. Ultimately, the absence of constraints facilitates a dangerous environment where fundamental freedoms are at risk and democratic principles are eroded.
