The female employee who made the allegations was later suspended from the team on full pay, and has been said to be 'very upset' about the whole situation.
Horner continues to vehemently deny any wrongdoing, and has stayed in his position throughout, overseeing a phenomenal start to the season for the world champions and their star driver Max Verstappen.
Now, The Sun have reported that the suspended employee has been 'grilled' by investigators amid the appeal process getting underway.
Whether or not the result of the investigation will be altered remains to be seen, but the female employee has reportedly hired the services of a new legal team.
The same publication is also reporting that the appeal process is expected to last until midway through May, suggesting a possible end date to the saga that has been rumbling on since before the 2024 season.
Previous reports had suggested that the saga would likely rear its head once more following the conclusion of the Chinese Grand Prix weekend.
