The National Transportation Safety Board has "revoked" Tesla's statusas a party to its investigation of a fatal crash that took place in Mountain View, California, in March.
However, Tesla maintains it withdrew from the probe.
An Apple engineer named Walter Huang was killed in the March 23 crash, driving a 2017 Tesla Model X with Tesla's Autopilot systems engaged.
Huang's family hired a law firm, Minami Tamaki, to explore their legal options, they announced this week. The firm has publicly stated that it believes the Autopilot feature in the Model X potentially caused Huang's death.
