A preliminary hearing is to be held today into the application by former opposition senator Arthur Williams who is challenging the grounds under which he was removed from the Upper House.
The matter is to be heard in chambers this morning in the Constitutional Court.
Williams wants the court to determine the validity of a signed, undated resignation letter used by Leader of the Opposition Andrew Holness to remove him from the Senate.
Williams and Dr Christopher Tufton were booted from the Senate last November by Holness.
It came to light that Holness had used undated resignation letters they wrote almost two years ago to secure their removal.
However, Williams, who has admitted to crafting the letters, said the letters were for a specific purpose.
He has argued that the Opposition Leader breached his constitutional rights when he submitted his resignation letter to the Governor General.
The former Senator had sought to bar Holness from filling the Senate seat but his application was denied.
