Step 1: Principle of precedent.
A precedent is binding until it is overruled or abrogated by a higher authority or replaced by legislation.
Step 2: Clarification.
- Public opinion does not affect precedent directly.
- Res judicata relates to finality of cases, not precedent.
- Lis pendens deals with property disputes during litigation.
Step 3: Conclusion.
Hence, option (b) is correct.
