Voadam's argument is rubbish when you look at the 3.5 rules.
However in the 3.0 rules, it seemed quite clear that you could ignore your quest if you were willing to take the consequences.
Here is the 3.0 rules
It seems self contradictory as well, using "must" and then "attempts"
Geas/Quest
Enchantment (Compulsion) [Language-Dependent, Mind-Affecting]
Level: Brd 6, Clr 6, Sor/Wiz 6
Components: V
Casting Time: 1 action
Range: Close (25 ft. + 5 ft./2 levels)
Target: One living creature
Duration: 1 day/level or until discharged (D)
Saving Throw: None
Spell Resistance: Yes
A geas places a magical command on a creature to carry out some service or to refrain from some action or course of activity, as desired by the character. The creature must be able to understand the character. While a geas cannot compel a creature to kill itself or perform acts that would result in certain death, it can cause almost any other course of activity. The geased creature
must follow the given instructions until the geas is completed, no matter how long it takes. If the instructions involve some open-ended task that the recipient cannot complete through his own actions, the spell remains in effect for a maximum of 1 day per caster level. Note that a clever recipient can subvert some instructions.
If the subject is
prevented from obeying the geas for a whole day, the subject takes 3d6 points of damage each day he does not attempt to follow the geas/quest. Additionally, each day he must make a Fortitude saving throw or sicken. A sickened creature moves at half his normal speed and suffers –4 penalties on both Strength and Dexterity. He heals damage at one-tenth his normal rate and cannot benefit from any magical healing effects. A sickened creature must make a Fortitude save each day or become crippled. Once crippled, the subject is effectively disabled (as if he had 0 hit points) and can’t choose to take strenuous actions. These effects end 1 day after the creature
attempts to resume the geas/quest.
A geas (and all penalties) can be ended by limited wish, remove curse (only if the remove curse’s caster level is at least two higher than the character’s caster level), miracle, or wish. Dispel magic does not affect a geas.
Wizard and bards usually refer to this spell as geas, while clerics call the same spell quest.
