Final answer:
The Gideon case enforces due process and limits the power of government by ensuring the right to an attorney for individuals who cannot afford one.
Step-by-step explanation:
The case of Gideon v. Wainwright (1963) enforces due process and limits the power of government by ensuring that individuals have the right to an attorney during legal proceedings. This case established that states must provide an attorney to defendants who cannot afford to pay for one. By guaranteeing legal representation to those who cannot afford it, the Gideon case prevents the government from arbitrarily denying access to legal representation, safeguarding the principle of equal protection under the law.
