Definitions for "Omnibus bill"
A draft law before a legislature which contains more than one substantive matter, or several minor matters which have been combined into one bill, ostensibly for the sake of convenience. In reality, such bills sometimes contain unpopular or less valuable matters which it is hoped will be passed because of the value of other parts of the bill. The omnibus bill is an "all or nothing" tactic.
from the Latin meaning "for all," an omnibus legislative bill contains many miscellaneous provisions, as in the omnibus budget bill that Republicans hope to push through Congress in the fall of 1995.
A bill regarding a single subject that combines many different aspects of that subject.
