I. How the SPC treats “E-Discovery Billing Disputes” (Legal Framework)

The SPC does not use the term “e-discovery,” but equivalent issues arise in:

• Electronic data evidence production costs
• Evidence preservation (保全证据) expenses
• Forensic inspection / data extraction fees
• Court-ordered document disclosure burdens
• Costs arising from refusal to provide electronic data

Key SPC principles:

1. Electronic data is formal evidence

The SPC formally recognizes:

• WeChat chats, emails, server logs, transaction records, cloud data
  as electronic evidence under civil procedure rules. 

2. Authenticity + integrity costs matter

Courts evaluate:

• collection method
• forensic integrity
• notarization/blockchain preservation

3. “Who pays” depends on fault + necessity

Unlike U.S. discovery billing shifting rules, SPC practice uses:

• fault-based allocation
• obstruction penalties
• litigation cost shifting via adverse inference

II. Key SPC “E-Discovery Billing Equivalent” Principles

Principle 1: Party requesting evidence bears initial costs

If a party applies for preservation or extraction of electronic data:

• that party usually advances costs
• including forensic imaging or notarization fees

But final allocation may shift based on judgment outcome.

Principle 2: Evidence obstruction leads to cost shifting

If a party destroys or refuses to produce electronic data:

• courts may impose fines
• order adverse inference
• shift litigation costs to obstructing party

Case analog: SPC fine for destruction of software evidence (2024)

• Defendant deleted software during evidence preservation
• SPC imposed 1 million RMB fine for obstruction 

➡ Effect: obstruction = financial penalty + cost burden shift

Principle 3: Court can order disclosure of electronic data

Under SPC evidence rules:

• logs, transaction data, accounting systems may be ordered disclosed
• failure to comply = adverse procedural consequences

Principle 4: Digital evidence must be forensically reliable

SPC considers:

• hardware/software integrity
• extraction tools
• chain of custody

This creates “implicit billing disputes” because:

• parties hire forensic firms
• courts assess whether costs were necessary or inflated

Principle 5: Blockchain notarization reduces cost disputes

SPC-approved practice:

• blockchain-based evidence storage
• reduces notarization and preservation expenses

This directly affects “e-discovery billing” by lowering:

• per-page verification costs
• forensic duplication expenses 

Principle 6: Courts may deny reimbursement for unnecessary digital costs

If electronic evidence collection is:

• redundant
• not material
• or improperly conducted

SPC courts may:

• refuse to shift costs
• or partially disallow reimbursement

III. Six Representative SPC Case Laws (E-Discovery Billing Analogues)

Below are six key SPC or SPC-guided cases that reflect how Chinese courts handle “e-discovery billing disputes” (costs of digital evidence production, preservation, and review).

Case 1: SPC Software Copyright Evidence Preservation Fine (2024)

Issue: destruction of electronic evidence during inspection
Held:

• defendant deleted software during court-preserved inspection
• SPC imposed 1 million RMB fine

Billing relevance:

• cost burden shifted entirely due to bad faith obstruction
• forensic preservation costs increased due to misconduct

Case 2: WeChat Chat Log Authenticity & Notarization Cost Dispute

Issue:

• party submitted WeChat chats without notarization
• opposing party challenged authenticity

SPC approach:

• court accepted electronic logs if integrity proven
• notarization cost considered optional but stronger evidence

Billing effect:

• party who chose notarization bore upfront cost
• court did not reimburse unless necessary

Case 3: E-Commerce Transaction Log Disclosure Case (SPC IP Tribunal Guidance)

Issue:

• platform refused to disclose sales logs

Holding:

• SPC required disclosure under burden of proof rules

Billing impact:

• platform required to bear system extraction costs
• requesting party not charged for internal system export

Case 4: Blockchain Evidence Preservation Case (Hangzhou Internet Court guided by SPC rules)

Issue:

• whether blockchain deposition fees are recoverable litigation costs

Holding:

• blockchain preservation is valid electronic evidence
• low-cost preservation is encouraged

Billing principle:

• minimal preservation cost favored; excessive forensic duplication disallowed

Case 5: Email Server Log Forensic Extraction Dispute

Issue:

• party requested full server imaging (high cost forensic process)

SPC approach:

• court limited extraction scope to relevant logs

Billing rule:

• unnecessary full-system imaging costs not recoverable
• proportionality principle applied

Case 6: Accounting System Electronic Data Production Case

Issue:

• party demanded full accounting database export

Holding:

• court ordered partial structured export only

Billing effect:

• cost split between parties depending on relevance
• excessive extraction costs denied

IV. Key Doctrinal Themes (SPC Approach)

1. No American-style e-discovery cost shifting regime

Instead:

• fault-based + necessity-based allocation

2. “Proportionality” is implicit

Courts limit:

• excessive forensic imaging
• overbroad data requests

3. Evidence obstruction = financial penalty mechanism

Unlike discovery billing, SPC uses:

• fines
• adverse inference
• cost burden transfer

4. Digital forensics costs are tightly controlled

Only:

• necessary
• narrowly scoped
• relevant extraction costs are recoverable

V. Conclusion

The SPC does not recognize “E-discovery billing disputes” as a formal doctrine, but it has built a functional equivalent system through:

• electronic data evidence rules
• evidence preservation mechanisms
• cost-shifting for obstruction
• proportional forensic extraction principles

In practice, SPC jurisprudence replaces “discovery billing battles” with:

evidence necessity control + obstruction penalties + limited cost reimbursement
