Legal analysis rests on fundamental principles:
Rule of Law: Law, not arbitrary discretion, governs society. Everyone, including government, is subject to law. Predictability and stability are essential.
Precedent and Stare Decisis: Courts follow prior decisions (precedent) to ensure consistency and predictability. "Stand by things decided." Distinguishing cases or overruling precedent requires strong justification.
Textual Authority: Legal conclusions must be grounded in authoritative texts—statutes, constitutions, regulations, contracts, case law. Personal preferences are irrelevant.
Adversarial System: Truth emerges from competing advocates presenting strongest cases for each side. Lawyers have duty to zealously represent clients within bounds of law.
Burden of Proof: Party asserting claim bears burden of proving it. Standards vary: preponderance of evidence (civil), beyond reasonable doubt (criminal), clear and convincing evidence (some contexts).
Procedural Justice: How decisions are reached matters as much as outcomes. Due process, notice, opportunity to be heard, impartial tribunal are essential.
Statutory Interpretation Canons: Principles guide interpretation—plain meaning, legislative intent, avoiding absurd results, constitutional avoidance, rule of lenity (criminal statutes construed narrowly).
Legal Realism: Law is not purely logical or mechanical. Judges are humans influenced by facts, policy, and context. Understanding outcomes requires considering more than just rules.
法律分析基于以下基本原则：
法治原则：由法律而非任意裁量治理社会。包括政府在内的所有人都必须遵守法律。可预测性与稳定性至关重要。
遵循先例（Stare Decisis）：法院遵循先前判决（先例）以确保一致性与可预测性。“遵循已决之事”。区分判例或推翻先例需具备充分正当理由。
文本权威：法律结论必须基于权威文本——制定法、宪法、法规、合同、判例法。个人偏好无关紧要。
对抗制：真相源于对立双方的辩护人各自呈现最有力的案件。律师有义务在法律范围内热忱代表客户。
举证责任：主张权利的一方承担举证责任。证明标准不同：民事案件为优势证据，刑事案件为排除合理怀疑，部分情形为清晰且有说服力的证据。
程序正义：决策的作出方式与结果同等重要。正当程序、告知权、陈述权、公正法庭至关重要。
法律解释准则：指导法律解释的原则——平义解释、立法意图、避免荒谬结果、合宪性回避、刑法从严解释规则（刑事制定法需狭义解释）。
法律现实主义：法律并非纯粹逻辑或机械的产物。法官是受事实、政策及语境影响的人。理解判决结果需考虑规则之外的因素。
