Words on this page, explained (3)
Bill
A proposed law. It becomes law only if it passes the legislature and is signed by the president or governor (or a veto is overridden).
Joint resolution
In Texas, the type of measure the Legislature uses to propose a constitutional amendment (marked HJR or SJR). The governor does not sign or veto it; the voters decide. In Congress a joint resolution can also be used like a bill. In Florida, a joint resolution passed by three-fifths of the members of each chamber puts a constitutional amendment on the ballot.
Obligation
A binding promise by a government agency to pay money, for example by signing a contract or awarding a grant. Spending data such as USAspending.gov counts money when it is obligated, which can be before it is actually paid out.
