The ratio of the case primarily revolves around the principle that a party who unconditionally accepts a settlement or benefit under a certain package or agreement cannot later turn around and dispute or reject the terms of that package, especially if they have given up all prior disputes related to the matter. This is encapsulated in the maxim "qui approbat non reprobat," meaning "one who approbates cannot reprobate" (!) .

In this context, the court emphasized that once the appellant accepted the Migration Package unconditionally and abandoned all disputes relating to the License Agreement for the specified period, it was not permissible for the appellant to subsequently raise disputes or objections concerning those very issues (!) (!) . The court upheld the principle that acceptance of a package or settlement, which involves relinquishing certain rights or claims, binds the party to the terms and prevents retraction or rejection of those terms later on (!) .

Therefore, the core legal principle or ratio in this judgment is that unconditional acceptance of a settlement or package, which includes waiving prior disputes, estops the party from re-agitating those disputes subsequently. This reinforces the doctrine that benefits and burdens under an agreement are to be accepted together, and one cannot accept the benefits while rejecting the burdens or conditions attached to them.
