While the identity of the aggressor was unknown, (TV: The Three Doctors) as Omega's anti-matter universe was beyond the reach of the Matrix, (PROSE: The Legacy of Gallifrey) the President decided to use the last of their power to summon the Doctor's first two incarnations to help the current third incarnation to resolve this crisis. (TV: The Three Doctors)
His decision to break the Laws of Time met with criticism from his Chancellor, but the President had faith in his gamble since the Time Lords didn't have any better solution since the energy drain was difficult for them to sort out.
After this gamble proved successful, the President rescinded the Third Doctor's exile on Earth and restored his ability to travel through time and space, (TV: The Three Doctors) having been advised to do so by his High Chancellor Socra, who, when the President demanded an explanation, revealed to him the existence of (and his allegiance to) the Celestial Intervention Agency. Pandad decided to keep it secret from the populatiion despite the CIA's offer to go public, feeling that it might risk lessening the Gallifreyan people's faith in the Presidency.
The same President Pandad IV (PROSE: The Legacy of Gallifrey) fell victim an an experiment conducted bt the Rani. It had resulted in some of her lab mice growing to an enormous size: The mice then ate the President's pet, a cat, and bit the President himself, triggering a regeneration. The Rani exiled herself and became a renegade as a result of the incident. (TV: The Mark of the Rani) This ended the tradition of Lord Presidents of the Time Lords possessing intelligent cats for pets and advisors, a tradition which had begun with Rassilon himself and would not be brought back until Flavia (PROSE: The Legacy of Gallifrey) became Acting President after the Fifth Doctor ran off on the Time Lords. (TV: The Five Doctors)
