Provisional Measures – DTI imposed P20.60 per 40-kg bag provisional duty for 200 days (November–December 2001).
Formal Investigation – Tariff Commission conducted public hearings, plant visits, reviewed market share, production, capacity utilization, financial performance; issued Formal Investigation Report (March 2002) concluding no serious injury or threat and recommending against definitive measures.
DTI Secretary’s First Decision (April 5, 2002) – denied application based on Tariff Commission’s negative determination and a DOJ opinion holding the Secretary bound by that finding.

Concurrent Filings – Southern Cross sought temporary restraining order (TRO) in the Supreme Court and filed petition for review with the Court of Tax Appeals (CTA); Philcemcor moved to dismiss for forum-shopping.
Supreme Court Proceedings – oral arguments (February 18, 2004) framed issues: proper appellate forum, validity of CA decision, and propriety of TRO.
