Final answer:
Legal aid is a provincially funded service that provides legal assistance from a lawyer to individuals who cannot afford it. It was established as a constitutional right by the Supreme Court's decision in Gideon v. Wainwright.
Step-by-step explanation:
A provincially funded service for those who need legal assistance from a lawyer is called Legal aid. This service typically provides legal representation to individuals who cannot afford it. It is a result of the Supreme Court's decision in Gideon v. Wainwright (1963), which established the constitutional right to have a lawyer provided at the state's expense to all defendants accused of a felony. This ruling has led to an increased need for professional public defenders and ensures that everyone has the right to a fair trial, regardless of their financial situation. This helps ensure that everyone has access to justice and can receive legal representation when needed.
