MARIA CRISTINA FERTILIZER PLANT EMPLOYEES ASSOCIATION, ET AL., petitioners, vs. HON. TEODULO C. TANDAYAG, MARIA CRISTINA FERTILIZER CORPORATION, respondents. / MARIA CRISTINA FERTILIZER PLANT EMPLOYEES ASSOCIATION-ALU, ET AL., petitioners, vs. MARIA CRISTINA FERTILIZER CORPORATION, JOSE MARCELO and COURT OF INDUSTRIAL RELATIONS, respondents.

FACTS

The Maria Cristina Fertilizer Corporation and the Maria Cristina Fertilizer Plant Employees Association had a collective bargaining agreement (CBA) expiring on December 31, 1967. In September 1967, the union submitted a draft for a new CBA. Negotiations ensued but proved fruitless, with the company proposing a simple renewal and later a wage increase offer that the union rejected. After a series of communications, including a union warning and a company suggestion for mediation by the Department of Labor, the union declared a strike on January 17, 1968, citing refusal to grant demands, violation of the Minimum Wage Law, anti-unionism, and unfair labor practices. The strike paralyzed company operations.
Subsequently, the company filed two parallel actions. First, on January 30, 1968, it filed a complaint for damages with a petition for a preliminary injunction in the Court of First Instance (CFI) of Lanao del Norte, alleging the strike and picketing were illegal. The CFI issued an injunction. Second, on January 31, 1968, the company filed an unfair labor practice charge against the union with the Court of Industrial Relations (CIR). The CIR’s prosecution division filed a corresponding complaint. Conversely, the union also filed an unfair labor practice charge against the company with the CIR, which was similarly prosecuted.

ISSUE

The primary issue consolidated in these petitions is whether the Court of First Instance had jurisdiction to entertain the company’s action for damages and to issue an injunction, given that the acts complained of—the strike and picketing—were simultaneously the subject of unfair labor practice cases pending before the Court of Industrial Relations.

RULING

The Supreme Court ruled that the CFI had no jurisdiction. The legal logic is anchored on the doctrine of primary jurisdiction. The acts constituting the alleged illegal strike and picketing, which formed the basis for the damages claim in the CFI, are intrinsically intertwined with the unfair labor practice charges filed in the CIR. The Industrial Peace Act ( Republic Act No. 875 ) vested the CIR with exclusive jurisdiction over cases involving unfair labor practices. Since the determination of whether the strike was illegal or a legitimate concerted activity is a question that falls squarely within the CIR’s specialized competence, the CFI could not properly adjudicate the damages action without first encroaching upon this exclusive domain.
The Court emphasized that allowing the CFI to proceed would risk conflicting decisions on the same factual nucleus—the legality of the strike. The injunctive relief granted by the CFI was likewise void for lack of jurisdiction. Consequently, the case before the CFI should be dismissed. The matters were properly within the purview of the CIR, where the consolidated unfair labor practice cases (CIR Case Nos. 109-ULP-ORO and 111-ULP-ORO) should proceed to resolve the underlying labor dispute, including the validity of the strike and the parties’ respective claims. The ruling reinforces the principle that courts of general jurisdiction should yield to specialized quasi-judicial agencies on matters within their exclusive expertise to promote orderly administration of justice.
