Yes, under certain conditions, UN Security Council (UNSC) resolutions can override aspects of state sovereignty, especially when acting under Chapter VII of the UN Charter. However, this override is limited, must be for maintaining international peace and security, and is subject to legal, political, and humanitarian constraints.

When and How Can It Override Sovereignty?
Legitimate Grounds:
Preventing genocide or crimes against humanity
Enforcing peace after conflict
Nuclear non-proliferation measures
Sanctions and embargoes

But Not Absolute:
UNSC resolutions cannot override
A State's core constitutional identity or existence.
Peremptory norms (jus cogens) of international law (e.g., prohibition on torture, genocide).
Human rights obligations, unless explicitly justified and proportionate.
Yes, the UNSC can override certain aspects of state sovereignty, but only when acting under Chapter VII for purposes like preventing war, mass atrocities, or global threats. Such power is exceptional, not general, and must be proportional, legal, and justified under international law.
