Title
IN RE: Del Castillo
Case
A.M. No. 10-7-17-SC
Decision Date
Feb 8, 2011
Justice Del Castillo was accused of plagiarism in *Vinuya v. Romulo*; the Court ruled no malicious intent, distinguishing judicial writing from academic standards, upholding dismissal of charges.

Case Summary (A.M. No. 10-7-17-SC)

Judicial Citation Practices Under Stare Decisis

• The judicial function rests on stare decisis: judges routinely cite precedents, statutes, and authoritative commentary to apply established law, rather than produce wholly original scholarship.
• Judicial writings serve to decide disputes and ensure correctness and fairness, not to advance original research.
• Courts and practitioners may lift tested language from public-domain or common-property legal materials without fear of disciplinary or liability concerns, so long as there is no fraudulent intent.

Distinction Between Academic and Judicial Writing

• Academic publishing demands originality, rigorous attribution, and often punitive measures for any unattributed copying.
• Judicial writing prioritizes accuracy and fidelity to law but relieves judges from being treated as literary authors; the emphasis is on correctness of legal outcome, not literary novelty.
• Judges are ethically bound to avoid misrepresentation of sources but may rely on publicly available legal commentary and previous court language without strict academic attribution standards.

Judges’ Exemption from Plagiarism Claims

• Leading authorities, such as the International Bar Association and Joyce C. George’s Judicial Opinion Writing Handbook, recognize that judges deciding cases are generally exempt from plagiarism claims, since their purpose is adjudication, not literary creation.
• The public domain status of judicial decisions and the risk-averse need for precise legal language further justify the practice of adopting established formulations.

Committee Findings on Drafting and Attribution

• The Ethics Committee found that initial drafts of the Vinuya decision included proper attributions to all sources.
• Court-employed researchers accidentally omitted three foreign-author citations while cleaning up the final draft—without any motive to deceive.
• Remaining citations to earlier source materials demonstrated that Del Castillo never presented others’ work as his own.

Application to Vinuya and Ang Ladlad Decisions

• In Vinuya v. Executive Secretary, Del Castillo’s ponencia engaged in detailed factual narration, issue-formulation, discussion of law, and systematic application to reach a fair outcome.
• The committee and en banc found no twisting of source materials or passing off of ideas.
• Similar allegations in Ang Ladlad v. Commission on Elections were examined and found equally without merit, as proper attributions existed despite formatting irregularities.

Dismissal of Reconsideration Motions

• Petitioners’ motion for reconsideration re-urged allegations of plagiarism, citation twisting, and gross neglect.
• The Court reaffirmed that no malicious or dishonest intent existed in Del Castillo’s work.
• The court dismissed both the original charges and the motions for reconsideration for lack of merit, preserving established practice that judicial decisions will not be annulled for inadvertent citation lapses.

Carpio Dissent: Jurisdiction and Copyright

• Justice Carpio argued that only Congress, by impeachment, may discipline Supreme Court justices for impeachable offenses, including betrayal of public trust.
• He maintained that the Court lacks jurisdiction to decide administrative complaints against its own members and should recall the Octobe
