No one could be Praetor without having first been Quaestor, or Consul without having held the praetorship.

Every candidate for the office of Quaestor must be at least thirty years old.

The number of Praetors was increased from six to eight; that of Quaestors, from twelve to twenty.

The Consuls and Praetors were to remain at Rome during their first year of office, and then go to the provinces as Proconsuls and Propraetors.
Three hundred new Senators, taken from the Equites, were added, and all who had been Quaestors were made eligible to the Senate.
The control of the courts was transferred from the Equites to the Senate.
On the death of Sulla, in 78, CRASSUS and LEPIDUS were chosen Consuls; but such was the instability of the times that they were sworn not to raise an army during their consulship.

Lepidus attempted to evade his oath by going to Gaul, and, when summoned by the Senate to return, marched against the city at the head of his forces.
