Captain America: Civil War. In the comics, the Super Human Registration Act tore the entire superhero community apart. ed in the wake of a disaster at Stamford, Connecticut, the SHRA required all superhumans to with the government. Some - such as Iron Man and Mr. Fantastic of the Fantastic Four - saw this as a necessary way of introducing ability to superheroism. Others, most notably Captain America, believed the SHRA to be an unjustifiable limit on their personal freedom.
The Sokovia Accords are the MCU's equivalent of the SHRA. Captain America: Civil War seemed to suggest they were introduced purely to police and manage the activities of the Avengers, who were split in half due to the heroes' philosophies and allegiances. But they seemed more of a plot device, with the split between Iron Man and Captain America swiftly becoming personal rather than philosophical. The precise of the Sokovia Accords were never disclosed, and even now it's unclear why Peter Parker was able to continue acting as a vigilante when his Spider-Man alter ego was neither an Avenger nor a signatory to the Accords.
Jessica Jones handled the Sokovia Accords rather better than the mainstream MCU. In part, this was because Marvel Television sought to find a way to make the Sokovia Accords relevant to their shows, and so they expanded them to argue that all superhumans were required to . This affected the Inhuman assets of Captain America: Civil War even more directly. Shaken by her mother's crimes, Jessica argued Alisa deserved to be imprisoned in the Raft, the superhuman prison introduced to hold powered individuals who were in breach of the Sokovia Accords. The threat of the Raft loomed again in Jessica Jones season 3, with Jessica ultimately allowing her closest friend Trish Walker to be taken there.
In the comics, the Raft was envisioned as the superhuman equivalent of Guantanamo Bay - a place where superhumans could be held without rights. The same idea was implied by Captain America: Civil War, because there it is situated in international waters, potentially meaning it sits outside of any government's jurisdiction and therefore human rights do not apply. This idea has yet to be explored in the mainstream MCU, although it's possible the Raft's status will be explored in a hypothetical Thunderbolts project going forward. Marvel Television, however, wasted no time discussing this concept; Jessica Jones season 2 added an even more fascistic element to the Sokovia Accords, noting a "special protocol" covers superhumans that means attorney/client privilege is revoked and there are no trials. According to Jessica Jones, prisoners on the Raft don't have visitation rights, and they are kept in solitary confinement for 23 hours a day.
The Sokovia Accords have had a background presence in the mainstream MCU, handled inconsistently based on the demands of the plot. Marvel Television did a far better job identifying their potential wider impact, and in Jessica Jones seasons 2 and 3 they subtly established just how harsh the Sokovia Accords truly are. It's striking that, unlike Captain America, Jessica never thought she could defy the Accords, and she never thought of overthrowing them; a street-level vigilante, she was under no illusions about her influence and agency in this regime. Thematically, this ties the Sokovia Accords themselves to some of the main themes of Jessica Jones - a smart storytelling approach by Marvel Television.
