The South Korean court rejected the appeal of Jang Suk Woo on Friday.

The CEO of K-pop record label Open World Entertainment is sentenced to six years for sexually assaulting three aspiring stars, two that were signed to his label.

Two of the girls were minors, according to the website Soompi.

The court rejected the CEO's claim that his sentence was unfair, in what the court claimed was in accordance with the law.

"Mr. Jang insisted that the assessment of the case was unjust but according to the criminal action law, that insistence can only be counted with the death penalty or a sentence of 10 or more years of prison," read the official court statement.

According to the charges, Jang sexually assaulted the three underage girls between November 2010 and March 2012.

"Mr. Jang, was arrested on April 13 with the charge of sexually assaulting 11 trainees who were under his agency," read an official statement from Open World Entertainment in 2012.

A K-pop "trainee" is someone being groomed by the record label to be a star. Many major artists in the genre, especially the members of top boy bands and girl bands are even sent to camps where they learn to sing, dance and act.

"Upon further police investigations, it is suspected that he has been abusing his trainees since 2008, with many of the trainees being in their teens at the time of the incidents."

The record label's statement went on to detail Jang's alleged behavior. 

"There are further allegations that the CEO would take out his trainees and celebrities under his label and would tamper with the trainee's alcoholic drinks," the statement read.

"He would then sexually assault the victims and would even force the male idol members to participate in the sexual assaults."

Jang received his six-year sentence in August and was also ordered to undergo a 40-hour sexual assault healing program.

The case has been making its way through over an appeal process that lasted over a year.

At a hearing back in November, Jang's lawyer defended his client as a successful, hard-working man.

"The defendant acknowledges and admits all charges against him," said Jang's legal counsel.

"However, the defendant worked hard for the spread of Hallyu and is a true businessman in the nation's entertainment industry."

The lawyer also denied rumors that Jang was involved in the criminal underworld.

 "There are a couple of misconceptions about the defendant," the lawyer said.

"There are reports of the defendant being related to criminal gangs and violence but that is not true. He has no relations with them."
