Maryland is set to become the 18th state in the United States to do away with capital punishment.
Supporters of death penalty repeal say the measure is expensive, racially biased and a poor deterrent against crime.
Opponents, meanwhile, argue that it is a necessary evil to punish those who commit heinous crimes.
Maryland currently has five men waiting on death row, though the new measure paves the way for the governor to commute their sentences to life in prison.
Maryland’s last execution took place in 2005, during the term of Republican Gov. Robert Ehrlich.
