(a) Review of Form: All courts, not just the Constitutional Court, can review the form of laws.
(b) Deficiencies in Form: Significant form deficiencies that affect legislative intent can lead to annulment, and compliance with internal regulations is mandatory.
(c) Violation of Internal Rules: Violations of significant procedural rules may lead to annulment, but not all violations are grounds for it.
(d) Review of Constitutional Amendments: The review is limited to compliance with proposal majority, voting majority, and transparency in the final vote.
