Which legal principle emphasizes that juveniles should be treated differently than adults due to their age?

The legal principle that emphasizes that juveniles should be treated differently than adults due to their age is parens patriae. This doctrine, which translates from Latin as "parent of the nation," allows the state to step in and act as a guardian for minors who cannot protect themselves. It reflects the idea that children's age and developmental status warrant a different approach in the legal system, focusing more on rehabilitation than punishment.

Juveniles are recognized as being in a formative stage of life where they may not fully comprehend the consequences of their actions or possess the same decision-making capabilities as adults. Therefore, parens patriae serves as the foundation for a separate juvenile justice system, which aims to support and rehabilitate rather than simply penalize young offenders. This principle underscores the belief that society has a duty to nurture and reform juveniles, recognizing their potential for change and growth.

In contrast, the other legal principles mentioned do not focus on the unique needs of juveniles.
