South Korea's criminal justice system becomes fundamentally unstable as each new administration dismantles and rebuilds prosecution authority, until legal predictability itself becomes a casualty of democratic transition.
What begins as legitimate democratic debate over prosecutorial power calcifies into a destructive ritual: each incoming president dismantles the predecessor's justice architecture and builds a new one loyal to the current coalition. By the third cycle, institutional knowledge has evaporated. Career prosecutors, uncertain whether their agency will exist in four years, stop building complex cases. White-collar criminals learn to time their schemes to the political calendar, knowing that investigative threads snap at every transition. Foreign investors begin pricing 'legal continuity risk' into South Korea's sovereign assessments. The Constitutional Court's warning goes unheeded, and by 2030, South Korea's criminal justice system functions less like a branch of government than like a seasonal pop-up store.
Prosecutor Kim Dohyun sits in a half-empty office in Gwacheon on his last day before mandatory reassignment in March 2029. Three years of evidence on a massive tax fraud case fill boxes that no one at his successor agency will open, because the case filing system is incompatible and the new leadership has different priorities. He labels the final box, locks the door, and takes the elevator down past a lobby where workers are already removing the old agency's nameplate.
Some constitutional scholars argue that periodic institutional reset is a feature, not a bug, of vigorous democratic accountability. The alternative — an entrenched, unreformable prosecution service — historically led to the very abuses that triggered reform in the first place. The real failure may be not the oscillation itself but the absence of a bipartisan constitutional framework to contain it.
