The top court upheld a lower court conviction of a former Samsung executive for sabotaging labor union activities at an amusement park run by a group affiliate.

The Supreme Court on Thursday confirmed the 16-month prison sentence for Kang Kyung-hoon, a former Samsung Electronics vice president, on charges of obstruction of business and violations of union laws.

Kang was indicted for planning and leading group-wide efforts to neutralize the labor union at Everland,  South Korea's largest theme park operated by Samsung C&T Corporation, between 2011 and 2018.

Kang and around ten other former or currently serving executives and employees were accused of and later convicted for their involvement in launching a separate management-controlled union and the leaking of sensitive personal data.

In an unrelated case, Kang was convicted of orchestrating a similar union sabotage in 2013, when a similar labor group was formed at Samsung Electronics Service, a subsidiary of Samsung Electronics.
