Null and void
The two elements mean the same thing, so there is no need to use both.
As a drafting point, it’s a dangerous phrase. If doing (or not doing) something renders a contract null and void (or terminated), you may not be able to sue the breaching party because there is no longer any underlying obligation. You are better to say that the non-breaching party is relieved from performance of the contract (but can still sue on it).
Rate of speed
This phrase appears, according to CanLII, in 4,173 Canadian cases and 126 statutory provisions.
Speed is, by definition, the rate at which something moves. So, just speed.
No, just tenth anniversary.
The anni– bit derives from the Latin annus, which means ‘year’ and also gives us annual.
