Samsung lawyers denied on Thursday all charges brought against Lee Jae-yong, the billionaire heir to Samsung, and questioned the legitimacy of the indictment in a massive corruption scandal that has ensnared the country’s president. Lee’s lawyers told a preliminary hearing that prosecutors are unfairly trying to create an impression Lee is guilty by mentioning a past conviction of his father and by depicting Lee as having absolute control over a strategy office that allegedly engaged in bribery.
