K-pop group NewJeans has lost a legal battle to leave its record label Ador.

A South Korean court on Tuesday ruled that the act's contract with the label, which runs until 2029, remains valid.

The group's five members - Hanni, Hyein, Haerin, Danielle, and Minji - announced last year that they were unilaterally leaving the agency, citing mistreatment and manipulation.

The group has said it will appeal the ruling, according to local media reports.

NewJeans said it is impossible to return to Ador and continue their activities as normal, the reports said.

The Seoul Central District Court rejected NewJeans' argument that the dismissal of former Ador CEO Min Hee-jin, who was also the group's mentor, constituted a breach of contract. NewJeans alleged that her dismissal broke their trust with the agency.

The case stunned South Korea where record labels wield large amounts of power and tightly control their stars. It is highly unusual for artists to rebel against them.

Formed in July 2022, NewJeans, whose members are aged from 17 to 21, had enjoyed rapid success before their dramatic fallout with the agency.

Their first single Attention topped Korean charts right after their debut, while their hit song SuperShy made multiple best of the year lists at the end of 2023, including those compiled by Rolling Stone, NME, and Billboard Magazine.

Critics had called them a game-changer as their blend of 1990s R&B and sugar-coated pop melodies broke through a K-pop scene dominated by electronic beats.

What led us here?

Tuesday's ruling follows a year-long standoff between the chart-topping group and its agency.

The group's announcement to split from Ador, made in November last year during a press conference, stemmed from a prolonged and public dispute between Min Hee-jin and the label, as well as its parent company, Hybe - South Korea's biggest music label, whose client list includes K-pop royalty such as BTS and Seventeen.

Tensions between Min and Hybe started in April 2024 when Hybe launched audits into Ador, managed by Min, demanding her resignation.

Min rejected Hybe's allegations that she planned to go independent. In August, she was dismissed as Ador's CEO.

The band soon issued an ultimatum demanding that Min be reinstated. When Hybe refused, the members publicly aired grievances against the label, including claims it deliberately undermined their careers.

One member, Hanni, alleged that she suffered workplace harassment while working with the label.

In December, Ador filed a lawsuit asking the court to confirm the contract's validity with the group.

As disputes unfolded, the group attempted to rebrand as NJZ in February, planning to release a new song, but promotions were halted by court order.

Despite the restrictions, they performed in Hong Kong, where they announced a hiatus.

After the court injunction, the group referred to the decision as a shock, but they pledged to navigate the turmoil together.
