International Union, United Automobile, Aerospace & Agricultural Implement Workers, Local 283 v. Scofield
The Supreme Court ruled that a party who won completely before the National Labor Relations Board has the right to intervene when the losing side takes the case to a federal appeals court, rather than being limited to filing a friend-of-the-court brief.
The decision applies whether the winner was the company accused of an unfair labor practice or the union that filed the charge, and it aims to prevent duplicate lawsuits and unfair treatment of parties simply because they succeeded before the agency.
“These considerations lead us to the assumption that Congress would not intend, without clearly expressing a view to the contrary, that a party should suffer by his own success before the agency.”
The Court's core reason for letting winning parties intervene in the appeal.
How it got here: In both cases the Board ruled for one side, the loser sought review in a federal appeals court, and the winning party's motion to intervene was denied, leaving it only as a friend-of-the-court.
The Case in Depth
What happened
Two labor disputes reached the Court together. In one, a union that had been cleared by the Labor Board of unfairly fining members who exceeded incentive-pay limits wanted to join the court fight when the fined employees appealed. In the other, a union that had won an order against a bearing manufacturer for blocking its own time studies of factory jobs wanted to join when the company appealed that order.
The question before the Court
If a union or company wins its case before the National Labor Relations Board, can it still jump into the appeals court fight when the losing side asks a court to overturn that win?
Why it matters
Unions and employers who win their case at the Labor Board no longer risk being shut out of the courtroom when the other side appeals. They can now help shape the record, file briefs, argue in court, and later seek Supreme Court review themselves — protections previously reserved for the losing party who had to defend against the appeal.
What changes now
Both cases are reversed and sent back to the appeals courts that had denied intervention. The union in each case may now participate as a full party — helping shape the record, filing briefs, taking part in oral argument, and potentially seeking further review — rather than being limited to an amicus brief. Going forward, successful parties before the Labor Board in other cases can rely on this ruling to intervene in appeals filed by the side that lost.
What this does not decide
The Court did not decide the underlying merits of either labor dispute — whether the union's fines were lawful or whether the company had to allow the union's time studies. It also limited its ruling to intervention in Labor Board review proceedings specifically, not agency appeals generally.

How the Court got there
The legal reasoning, step by step
- The Court read the Labor Act's review provision, which lets any 'person aggrieved' by a Board order seek court review, and treated it as the starting point for figuring out who should also be allowed to join an appeal already underway.
- Because the statute itself is silent on intervention at the appeals-court stage, the Court looked at the overall design of the Act and its goal of resolving labor disputes with 'a minimum of technical requirements' and without unnecessary duplication of proceedings.
- The Court reasoned that denying intervention to the winning party would force a second, nearly identical appeal later if the case were sent back to the Board, wasting judicial resources and inviting parties to shop for favorable circuits.
- The Court also reasoned that letting the winning party join the first appeal is fairer, since it lets that party present its arguments before a court that has not yet formed its views, and it can then seek Supreme Court review directly rather than being at the mercy of the government's decision whether to ask for review.
- Turning to the union that had won as a charging party, the Court rejected the argument that only the Board represents the public interest, holding that the labor statute blends public and private interests and does not shut out the winning private party from the appeal.
- Because both charged parties and charging parties who win before the Board face the same practical stake in the outcome of the appeal, the Court concluded that Congress must have intended both types of winners to have a right to intervene rather than being downgraded to a mere friend-of-the-court.
