Nissan sues Ghosn's sister while Renault finds no irregularities in his pay

Nissan sued ousted chairman Carlos Ghosn's sister on Tuesday in a Rio de Janeiro court for "unjust enrichment," according to judicial records seen by Reuters. The suit is the latest twist to a bitter legal fight between Ghosn and Nissan over the contents of a beachfront apartment that the former executive used during his trips to Brazil. Brazilian-born Ghosn is accused of having underreported his income while leading the Japanese carmaker and diverting company funds for his personal use.
