Commissions consisting of fifteen councilors who examine, propose, and discuss the implementation of new laws that are on their way to being presented on the floor of the council. Every six months, the council elects two captains regent to be the heads of state. The captains are chosen from opposing parties so that there is a balance of power. They serve a six-month term. The investiture of the captains regent takes place on 1 April and 1 October in every year. Once this term is over, citizens have three days in which to file complaints about the captains' activities. If they warrant it, judicial proceedings against the ex-head(s) of state can be initiated. The practice of having two heads of state, like Roman consuls, chosen in frequent elections, is derived directly from the customs of the Roman Republic. The council is equivalent to the Roman Senate; the captains regent, to the consuls of ancient Rome. It is thought the inhabitants of the area came together as Roman rule collapsed to form a rudimentary government for their own protection from foreign rule. San Marino is a multi-party democratic republic.

The 2008 general election was won by the Pact for San Marino with 35 seats in the Grand and General Council against Reforms and Freedom's 25. On 1 October 2007, Mirko Tomassoni was elected as captain regent, making him the first disabled person elected to that office. San Marino has had more female heads of state than any other country: 15 as of October 2014, including three who served twice. With regard to the legal profession, while the Order of Lawyers and Notaries of the Republic of San Marino () exists, there is no clear indication as to how demographic groups have fared in the legal field. On 1 April 2022, 58-year-old Paolo Rondelli was elected as one of the two captains regent, its heads of state. He had previously been the Ambassador to the United States and is the world's first openly gay head
