Mission briefing
Unit 1A (How Courts Treat Electronic Evidence) gave you five questions a court asks about an electronic record. This unit builds a map of five gates from them, for the lawyer who must get a record in, and for the lawyer who must test it. The map adds hearsay and fairness, treats integrity as part of authenticity, and puts weight after the gates.
Focus: five gates in a fixed order, the two gates that cause most trouble (hearsay, and original or copy), and four ways legal systems open the gates. This unit is general knowledge. It is not legal advice. Rules of professional conduct differ by country, so check with your own bar or regulator.
Learning objectives
By the end of this unit, you will be able to:
- Put an electronic record through five gates, in order.
- Separate admissibility from weight, and say which argument belongs where.
- Explain hearsay, and how a business-records rule lets a record in.
- Tell a record a person wrote from a record a machine made, and say why it matters.
- Compare how five legal systems prove a copy of an electronic record.
Why this matters to you
- Lawyers and firms: one missed gate can keep out a record that would have won the point. The same map shows you where to object.
- Law students: every later unit in this course is a closer look at one gate.
1. One map, two users
A party that offers a record is its proponent. The party that tests it is the opponent. Both use the same map. The proponent plans a way through each gate before the hearing. The opponent asks at each gate, "Has this really been shown?"
The map is neutral. It serves the prosecution and the defence, the claimant and the defendant.
2. The five gates
Most legal systems ask these questions in some form. The order matters, because a record that fails an early gate never reaches a later one.
| Gate | The question | A typical objection |
|---|---|---|
| 1. Relevance | Does the record make a fact in the case more or less likely? | "This chat is about another deal." |
| 2. Authenticity | Is the record what the proponent says it is? | "Nothing links this account to my client." |
| 3. Hearsay | Is the record a person's out-of-court statement, used to prove that the statement is true? | "The author is not here to be questioned." |
| 4. Original or copy | Is this form of the record one that the law accepts as proof of its contents? | "This is a retyped extract, not the record." |
| 5. Fairness | Should the court still keep it out, because it would mislead, or because of how it was obtained? | "It was taken in an unlawful search." |
After the gates comes weight: how much the record proves. Unit 1A (How Courts Treat Electronic Evidence) drew this line. Keep to it. "The clock may have been wrong" is usually an argument about weight. "No one has shown where this file came from" is an argument about a gate.
Not every country has every gate. Some have no hearsay rule in this form. Some let the judge weigh almost everything. But the questions do not go away. In such a system they are asked when the judge weighs the proof.
3. Gate 1: relevance
State the fact you want to prove. Then say, in one sentence, how the record makes it more or less likely. If you cannot, the record is not ready.
Electronic records fail here in two ways. First, volume: a party offers 4,000 messages when six matter. Second, context: a message is relevant only when read with the messages around it. Choose, and be ready to produce the rest if the other side asks.
4. Gate 2: authenticity
Someone must show that the record is what it is claimed to be: this person's account, this camera's footage, this company's log. The proof may come from a witness, from a certificate, from the record's own features, or from a legal presumption. Unit K2 (Proving Electronic Records: Certificates, Presumptions and Witnesses) covers these routes in detail. An exhibit filed with no proof of its source has not passed gate 2.
5. Gate 3: hearsay and business records
Hearsay is, in broad terms, a statement that a person made outside the courtroom, offered to prove that what the statement says is true. Many legal systems limit it. The reason is simple. The court cannot watch the person give the statement, and the other side cannot question that person.
Take an email that says, "I delivered the goods on Monday." If the email is used to prove that the seller wrote to the buyer that week, the email is being used as an event. If it is used to prove that the goods were delivered on Monday, the email is being used for its truth. Only the second use meets the hearsay rule.
So ask two things of every record:
- What is it offered to prove? The fact that words were said, or the truth of the words?
- If the truth, is there a way through? Systems with a hearsay rule also have exceptions.
The exception that matters most for electronic records is the business-records rule. Its pattern is much the same in many systems:
- the record was made in the ordinary course of a business or other regular activity;
- it was made at or near the time, by a person with knowledge, or from information that such a person supplied;
- making such records was a regular practice.
The rule has a firm limit in many systems. A document that was written for the case, or for the investigation, is not an ordinary business record. A bank's ledger is a business record. A summary that the bank's fraud team writes for the police is not. Ask for the underlying records.
6. Written by a person, or made by a machine?
Electronic records come in two kinds, and many are a mix.
- Computer-stored records hold what a person wrote or said: an email, a chat message, a note typed into a customer file. The computer is a filing cabinet. The words are a person's statement.
- Computer-generated records are made by a system with no person writing the content: a login log, a call record made by a switch, a timestamp, a hash value.
The difference decides which question the court asks.
For a stored record, the hearsay question applies in full, because a person made the statement. Who wrote it? Did the writer know the facts?
For a generated record, there is no person to question. In several systems such a record is therefore not treated as hearsay at all. The question moves to reliability: was the system working, and was it set up to record this correctly? The answer comes from evidence about the system, or from a presumption that the system worked. Unit K10, When Computers Are Wrong, shows what happens when that presumption is trusted too far.
For a mixed record, split it. A billing record may contain a customer name typed by a clerk (stored) and call times logged by the network (generated). Each part has its own test.
7. Gate 4: original or copy
Older rules asked for the original document to prove its contents. This is often called the best evidence rule.
For data, the idea of one original breaks down. So legal systems have moved in three directions:
- Redefine the original. An accurate printout or other readable output counts as an original.
- Abolish the rule. Contents may be proved by a copy, a printout or a transcript, and the argument becomes one about accuracy.
- Keep the rule, but set conditions for copies. A copy is allowed if a stated procedure is followed, such as a certificate.
In all three, the practical question is the same: can you show that this output accurately reflects the stored data? A hash value and a record of how the copy was made answer it. A retyped extract does not.
8. Gate 5: fairness
A record can pass four gates and still be kept out. Courts in many systems may refuse evidence if its value as proof is outweighed by the risk that it will mislead or unfairly harm a party. Many may also refuse evidence that was obtained unlawfully or unfairly. This gate protects rights, and it applies to both sides. Unit K8 (Unlawfully Obtained Evidence and Exclusion) covers it.
9. Four ways legal systems open the gates
Unit 1A (How Courts Treat Electronic Evidence) named four approaches: certificate, authentication evidence, presumption and free evaluation. They are answers to gates 2 and 4. Most countries mix them.
How five legal systems prove a copy of an electronic record
| Legal system | Main approach | The rule, in brief |
|---|---|---|
| India | Certificate | A copy or printout needs a certificate in a set form, signed by the person in charge of the device or of the relevant activity, and by an expert, each time it is filed. (Bharatiya Sakshya Adhiniyam, 2023, section 63) |
| Australia, federal courts | Authentication evidence and presumption | No special certificate. A copy or printout may prove the contents. A device that ordinarily works is presumed to have worked, unless evidence raises doubt. (Evidence Act 1995, sections 48, 51, 146 and 147) |
| United States, federal courts | Authentication evidence | The proponent must produce evidence sufficient to support a finding that the item is what it is claimed to be. A written certification by a qualified person is an optional short-cut. An accurate printout is an original. (Federal Rules of Evidence, rules 901, 902(13) and (14), 1001) |
| Canada, federal law | Authentication evidence and presumption | The proponent needs evidence capable of supporting a finding of authenticity. The best evidence rule is met by proof that the records system kept its integrity, and that is presumed in stated cases. (Canada Evidence Act, sections 31.1 to 31.3) |
| England and Wales | Presumption | No certificate since 2000. Courts presume that a computer was working properly unless there is evidence that it was not. A government review of that presumption opened in January 2025. |
Checked on 8 October 2026. India, Australia, the United States and Canada were read in the official text of the law. England and Wales was read in official prosecution guidance and a government paper, not in the statute itself. This table is for comparison. It is not advice. State, provincial and regional courts may differ.
No approach removes a gate. A certificate does not make a record true. A presumption can be displaced. If your country is not in the table, use the page "Find your own country's law".
Country note — Australia
Under the Evidence Act 1995 (Cth), relevant evidence is admissible unless the Act provides otherwise, and evidence that is not relevant is not admissible (sections 55 and 56). The hearsay rule is in section 59: it covers a previous representation "made by a person". Section 69 is the business-records exception, with its limit for representations made for a proceeding or in connection with a criminal investigation. Section 51 abolishes the old original-document rule, and section 48 sets out how contents may be proved. The fairness gate is in sections 135, 137 and 138. State and Territory courts apply their own Acts. The Australia-only unit 1C (Australia: Proving Electronic Records) takes these sections one by one.
Case file — five hurdles for one bundle of emails
What happened. Lightning struck a yacht. The owners and their insurer went to arbitration about the damage, then to a United States federal court in Maryland about what the arbitrator had been allowed to decide. Each side asked for judgment without a trial.
The evidence. Copies of emails between the lawyers, attached to both sides' filings to show what the arbitration agreement meant. No affidavit or other proof came with them.
The question. Could the court consider them?
The decision. No. In Lorraine v Markel American Insurance Co. (4 May 2007), the judge dismissed both requests and allowed the parties to file again with proper proof. He then set out the rules that any electronic record must pass, "like a series of hurdles": relevance, authenticity, hearsay, the original-writing rule, and unfair prejudice. A record that fails one is not admitted.
What it means in practice. Lawyer: plan each gate for each exhibit before you file. Officer: collect the proof of source with the record. Student: the frame is useful everywhere, but this is one trial-level court's opinion. It binds no other court, and the United States rules have changed since 2007.
Checked on 8 October 2026 against the court's opinion.
Worked example — the delivery dispute
Invented facts. Harbour Freight sues Lin Trading for unpaid transport. Harbour offers three items: (a) its dispatch system's log, showing a truck leaving at 06:10; (b) a driver's chat message, "Delivered to Lin's warehouse, 09:30"; (c) a spreadsheet that Harbour's accountant built last week for the lawyers.
- (a) is computer-generated. Hearsay is not the issue. Lin may ask how the system records times, and who can speak for it.
- (b) is a stored statement by a person, offered for its truth. Harbour needs a way through gate 3: the driver as a witness, or a business-records rule if drivers report every delivery this way.
- (c) was made for the case. It is not a business record. Harbour should offer the underlying entries, or call the accountant.
Activity — which gate?
For each objection, name the gate. Then say whether it is really about admissibility or about weight.
- "This printout was typed out again by a clerk."
- "The log is real, but the server clock was not checked that year."
- "The message proves only that someone said it, not that it happened."
- "The exhibit has no source and no witness."
Conclusion
You can now take an electronic record through five gates, keep weight apart from admissibility, apply the hearsay question and the business-records pattern, tell stored records from generated ones, and compare four approaches across five legal systems.
This unit builds on unit 1A, How Courts Treat Electronic Evidence. Next is unit K2, Proving Electronic Records: Certificates, Presumptions and Witnesses. Unit K3 (Integrity and Chain of Custody Under Challenge) tests integrity. Unit K10 (When Computers Are Wrong) tests machine reliability.
