Sulla then increased the number of magistrates elected in any given year, and required that all newly elected quaestors gain automatic membership in the Senate. These two reforms were enacted primarily to allow Sulla to increase the size of the Senate from 300 to 600 senators. This also removed the need for the censor to draw up a list of senators, since there were always more than enough former magistrates to fill the senate. To further solidify the prestige and authority of the Senate, Sulla transferred the control of the courts from the equites, who had held control since the Gracchi reforms, to the senators. This, along with the increase in the number of courts, further added to the power that was already held by the senators. Sulla also codified, and thus established definitively, the "cursus honorum", which required an individual to reach a certain age and level of experience before running for any particular office. Sulla also wanted to reduce the risk that a future general might attempt to seize power, as he himself had done. To this end he reaffirmed the requirement that any individual wait for ten years before being re-elected to any office. Sulla then established a system where all consuls and praetors served in Rome during their year in office, and then commanded a provincial army as a governor for the year after they left office.
