The eight-page letter, in which former HP contractor Jodie Fisher is believed to have accused Hurd of sexual harassment, is currently under seal in Delaware’s Court of Chancery as part of a shareholder suit filed against HP over the executive’s exit.
The law firm for the shareholder suit said last month it would publicise the letter, but Hurd’s lawyers have filed a motion to keep the letter private.
Hurd has denied having an inappropriate relationship with Fisher.
His spokesman said on Monday that “Mark acted properly in all respects.”
After leaving HP, Hurd joined rival Oracle as a co-president.
