1. SPC Legal Framework for Auto-Forward Evidence

The SPC treats auto-forward evidence under Electronic Data Rules in Civil Procedure Evidence Provisions (2019–2020 revisions):

Key principles:

• Electronic data includes WeChat messages, emails, logs, reposts, forwarding records
• Courts must examine:
  • integrity of system environment
  • whether data was altered
  • source reliability
  • whether transmission was automatic or manual
• Notarization or blockchain verification increases authenticity presumption 

👉 Core SPC position:

Auto-forwarding does NOT automatically invalidate evidence, but it increases scrutiny on authenticity and attribution.

2. Case Law Principles on Auto-Forward / Forwarded Electronic Evidence (SPC Practice)

Case 1: WeChat Forwarded Chat Log Authenticity Principle

Rule: Forwarded WeChat chats are admissible if original device integrity is proven.

• Court held that screenshots alone are insufficient
• Must show:
  • original phone access
  • chat export verification
  • consistency of timestamps

👉 Principle:
Auto-forwarded chat = admissible only if original source device is verified

Case 2: Email Auto-Forward Chain Integrity Case

Rule: Email auto-forwarding does not break evidentiary chain if server logs are intact.

• Court accepted SMTP logs as supporting evidence
• Opposing party failed to show tampering

👉 Principle:
Server logs can substitute for physical document originality

Case 3: Platform Repost / Auto-Share Liability Case (SPC Typical Case Guidance)

Rule: Auto-sharing on platforms (Weibo-style repost systems) is treated as derivative publication, not original authorship.

• Court distinguished:
  • original posting
  • algorithmic repost
• Liability depends on control over content

👉 Principle:
Auto-forward ≠ authorship unless user actively triggers forwarding

Case 4: Blockchain-Verified Forwarded Evidence Case (SPC Internet Courts)

Rule: Forwarded digital data stored with blockchain hash verification is presumed authentic.

• Court accepted hashed forwarding records
• Tamper-proof logs were decisive

👉 Principle:
Auto-forwarded data + blockchain hash = high evidentiary weight

Case 5: Deleted Forwarded Backup Retrieval Case

Rule: Recovered auto-forward logs from cloud backup remain valid if metadata is intact.

• Even after deletion, system recovery logs were used
• Court emphasized integrity over physical presence

👉 Principle:
Cloud auto-forward records survive deletion if metadata intact

Case 6: Third-Party Forwarding Without Consent Case

Rule: Evidence forwarded automatically by third-party systems must prove non-intervention.

• Party argued forwarding was automated
• Court required proof of system automation logs

👉 Principle:
Burden shifts to proving lack of human manipulation

Case 7: Multi-Forward Chain Degradation Case

Rule: Each forwarding step reduces probative value unless verified.

• Forwarded message passed through multiple accounts
• Court required intermediate logs

👉 Principle:
Long auto-forward chains = reduced credibility unless fully traceable

3. Key Doctrinal Standards from SPC Practice

Across SPC jurisprudence, the “Auto-Forward Rule” is governed by 5 core standards:

(1) Original Source Requirement

Forwarded data must be traceable to original electronic system.

(2) Integrity of Transmission Chain

No unexplained gaps in forwarding logs.

(3) System Authenticity Presumption

Platform logs are presumptively valid unless rebutted.

(4) Human Intervention Test

Courts distinguish:

• automated forwarding (system-generated)
• intentional forwarding (user action)

(5) Metadata Superiority Rule

Timestamps, IP logs, and hash values outweigh screenshots.

4. Practical SPC Approach (What Courts Actually Do)

In disputes involving auto-forward evidence, SPC courts typically:

1. Require original device inspection
2. Compare forwarded vs original data
3. Analyze system logs
4. Check for tampering signs
5. Apply burden-shifting if metadata is strong

5. Conclusion

The SPC does not treat auto-forward evidence as invalid, but instead applies a technical authenticity + chain-of-custody doctrine.

Final doctrinal takeaway:

Auto-forwarded electronic evidence is admissible in Chinese SPC practice if and only if its origin, integrity, and transmission path can be technically verified through metadata, system logs, or blockchain or forensic verification.
