A special election for the 133rd legislative district took place on December 5, following the death of Democratic state representative Daniel McNeill.

[3] Democratic state representative Leslie Acosta was re-elected during the 2016 elections, but later resigned after pleading guilty to charges of embezzlement.

Republican Superior Court judge Sallie Updyke Mundy was appointed by Governor Tom Wolf to the seat vacated by Justice Eakin and was subsequently confirmed on June 27, 2016.

A fourth seat became vacant due to then–Judge Sallie Mundy's elevation to the Supreme Court of Pennsylvania in July 2016.

In 2016, Governor Tom Wolf appointed three judges to the Superior Court, Carl Solano, Lillian Harris Ransom, and Geoffrey Moulton.
