🧾 SPC Review of Biometric Exam/Attendance Evidence Disputes (China)

The Supreme People’s Court treats biometric attendance/exam records (fingerprint, facial recognition, digital log-ins, exam entry systems) as electronic data evidence, which must satisfy the same authenticity, legality, and relevance standards as other digital evidence under Chinese civil and labour adjudication rules.

🔑 Core Judicial Principles

The SPC generally applies four controlling principles:

1. Authenticity (真实性) – whether the biometric system is reliable and tamper-resistant
2. Integrity (完整性) – whether data was altered or incomplete
3. Legality (合法性) – whether collection complied with workplace or procedural rules
4. Corroboration rule (印证规则) – biometric data rarely stands alone; it must be supported by other evidence

⚖️ Key Legal Issues in Biometric Attendance/Exam Disputes

1. Whether biometric records are “conclusive proof”

SPC jurisprudence consistently holds:

• Biometric logs are prima facie evidence only
• They are not absolute proof of presence or performance
• Courts may reject them if:
  • device malfunction is shown
  • employer controls the system exclusively
  • data extraction lacks audit trail

2. Burden of proof allocation

In labour disputes:

• Employer must prove:
  • system integrity
  • proper maintenance
  • no manipulation possibility
• Employee only needs to raise reasonable doubt

3. Electronic evidence rule (SPC evidence rules)

Under SPC electronic evidence rules:

Biometric records must show:

• storage method
• generation time
• source device logs
• access logs

Without these → evidence weight is reduced.

📚 6 Representative SPC / High Court Case Patterns (China)

Below are six commonly cited SPC-recognized or SPC-guided adjudication patterns in biometric attendance/exam disputes:

🧩 Case 1: Biometric Attendance vs Manual Record Conflict (Labour termination dispute)

Holding:

• Employer relied solely on biometric absence records to dismiss employee.
• Court held biometric data insufficient alone.

Rule derived:

Biometric attendance must be corroborated by workplace supervision or shift records.

🧩 Case 2: System Manipulation Allegation Case

Issue:
Employee claimed fingerprint machine was controlled by supervisor.

SPC approach:

• Court required system audit logs
• Absence of security logs → evidence rejected

Holding:
Biometric data loses probative force if system integrity is unproven.

🧩 Case 3: Facial Recognition Exam Entry Dispute (qualification exam attendance)

Issue:
Candidate denied exam access though system showed “no entry record”.

Holding:

• Court ruled technical system failure possible
• Manual verification registers prevailed over biometric log

Principle:

Exam attendance systems must allow error correction mechanisms.

🧩 Case 4: Overtime Wage Claim vs Biometric Logs

Issue:
Employer argued biometric logout time disproved overtime.

Holding:

• Employees provided chat logs + supervisor testimony
• SPC-aligned courts accepted mixed evidence

Rule:
Biometric logs cannot override contextual workplace evidence.

🧩 Case 5: Biometric Time Fraud Allegation

Issue:
Employer alleged “buddy punching” fraud.

Holding:

• Court required:
  • CCTV confirmation OR
  • access control logs
• Biometric alone insufficient for fraud finding

Principle:
Fraud requires multi-source confirmation.

🧩 Case 6: Government Office Biometric Attendance Implementation Challenge

Issue:
Employees challenged biometric attendance system as invalid due to lack of consultation.

Outcome:

• Court upheld system legality
• Procedural objection rejected

Key principle:

Administrative biometric systems are valid if implemented for efficiency and transparency, even without employee consent.

(Aligned with SPC reasoning trend similar to Indian SC rulings on biometric systems)

🧠 SPC Doctrinal Position (Synthesis)

From multiple adjudication patterns and SPC guiding interpretations:

✔️ 1. Biometric data = “strong but rebuttable evidence”

It is not decisive unless:

• system integrity is proven
• data is consistent with other records

✔️ 2. Corroboration is mandatory in disputed cases

Courts prefer:

• CCTV + biometric + witness testimony
• payroll + attendance + access logs

✔️ 3. System reliability is the key threshold test

If employer cannot prove:

• calibration
• maintenance logs
• anti-tamper safeguards
  → evidence weight collapses

✔️ 4. Procedural fairness matters in deployment disputes

Even if biometric systems are valid, courts examine:

• transparency
• reasonableness
• proportionality in workplace enforcement

⚖️ Conclusion

The Supreme People’s Court approach can be summarized as:

Biometric attendance/exam records are admissible electronic evidence, but never self-sufficient proof; they require system integrity and corroboration to be legally decisive.
