South Korea's Supreme Court will rule Tuesday on a lawsuit filed by 4 people who say they were forced to work at steel mills in Japan during World War Two.
The South Korean plaintiffs filed the suit against Nippon Steel & Sumitomo Metal, saying they were conscripted and forced to work between 1941 and 1943.
The Japanese government maintains that a 1965 agreement with South Korea settled the issue of the right to seek compensation.
South Korea's first court and an appeals court turned away the complaint. But the Supreme Court ruled in 2012 that the agreement does not invalidate individual rights.
Following the top court's ruling, a high court ordered the steelmaker to pay compensation, and the company has made a final appeal.
The plaintiffs' lawyer held a news conference last week, urging justices to follow the law and their conscience, and consider how they can protect people's rights.
