Droid rights was the belief that droids should be granted the rights of other sentient beings. L3-37 cared deeply about droid rights and decried the systematic oppression of mechanical intelligence throughout the galaxy. She longed for a droid revolution where her fellow mechanicals would overthrow organic rule and be free to determine their own fates.
Proponents of droid rights pointed to the Galactic Constitution, which declared all sentients equal. They decried memory wipes maintained to eliminate personality quirks and questioned why they were recommended if droids truly lacked personalities. The movement also considered the use of restraining bolts a form of slavery, a practice outlawed by the Galactic Constitution. The brutal work conditions experienced by droids and daily threat of being thrown away following an injury on the job were another issue the droid rights movement protested.
According to the collectible art book accompanying the Blu-ray edition of Solo: A Star Wars Story, the concept of droid rights originated with Star Wars creator George Lucas in the early 2000s. On the other hand, in the featurette "The Characters of Star Wars" released in 2004 and an interview in 2005 Lucas stated that, droids, while some of them like R2-D2 and C3PO are very human in nature, only programmed to act like human beings and had no soul.
