Article 3: Cancellation
Either Party may cancel this agreement. Once one party notifies the other with their intent to cancel, the Pact stays in effect for 10 days. If either party breaks the pact, it is considered null and void.
Some definitions.....
Null -adjective
1. without value, effect, consequence, or significance.
2. being or amounting to nothing; nil; lacking; nonexistent.
Void -adjective
1. having no legal force or effect; not legally binding or enforceable.
2. useless; ineffectual; vain.
So according to the definition of "Null" and "Void", Article 3: Cancellation, must be interpreted as this:
Either Party may cancel this agreement. Once one party notifies the other with their intent to cancel, the Pact stays in effect for 10 days. If either party breaks the pact, it (the pact as a whole) is considered null (nonexistant) and void (having no legal force or efect).
Any arguement about the legality of PC actions would be an arguement against the definition of the words used by TPF in the NAP.
