Advisory Commission Comments
Advisory Commission Comments [2002].
The amendment permits testimony of a witness outside the courtroom to be transmitted by contemporaneous audio-visual means to the trier of fact. Note that three conditions must be satisfied: good cause, compelling circumstances, and adequate safeguards.
Advisory Commission Comments [2003].
The new procedure in Rule 43.03 is designed to assist jurors in understanding conflicting expert testimony by providing judges and lawyers with considerable flexibility in the scheduling and mode of that testimony. On rare occasions, it may be helpful if expert testimony on the same subject be given in the same block of time rather than separated by days or weeks and given during each party's proof process. For example, in a tort case where both sides will present expert testimony on causation, jurors may benefit if the plaintiff's causation experts testify, followed immediately by the defendant's causation experts. This procedure may give the jurors a better way of resolving the issue of causation. Because of the tactical, financial, scheduling, and procedural issues raised by this new procedure, it can only be utilized with the consent of the court and all parties.
Advisory Commission Comments [2004].
New Rule 43.04 limits a trial court's consideration on motion rulings, particularly motion for summary judgment rulings, to certain designated materials. The amendment complements existing Rule 56.04.

Plain-English Summary
Rule 43.01 sets the baseline for trial testimony — it follows the Tennessee Rules of Evidence — and then carves out a detailed exception for testimony given from a remote location by audiovisual transmission. That exception is not casual: it requires good cause, compelling circumstances, and safeguards spelled out in the rule, and the standard is stricter for a party or expert witness than for an ordinary non-party lay witness, reflecting how much weight the rule places on having key witnesses appear in person. A party seeking remote testimony has to file a motion at least 60 days before trial, an opponent has 10 days to object, and the court has to rule at least 30 days out, absent an agreement or good cause to move those deadlines. The rule works through an extensive list of factors a court can weigh — everything from a witness’s age and need for an interpreter to camera angles, exhibit handling, and whether the value of face-to-face cross-examination outweighs the convenience of appearing remotely. A witness testifying from outside Tennessee has to sign a notarized consent submitting to the state’s perjury laws and the court’s authority, and the party offering the remote testimony bears the cost and logistical risk of making the technology work — equipment failure is not, by itself, grounds for a continuance.
Rule 43.02 addresses evidence at motion hearings rather than at trial: a court can decide a motion based on the parties’ affidavits, or can direct that some or all of the matter be heard through live testimony or depositions instead. Affidavits are the practical default for resolving most motions efficiently, though a court retains discretion to require live testimony when credibility is central to the outcome.
Rule 43.03 lets a court, with every party’s consent, depart from the usual order of proof so that competing experts on the same subject testify back-to-back rather than separated by each side’s broader case — a tool aimed at helping jurors follow and weigh conflicting expert opinions on complex, technical questions like causation.
Rule 43.04 requires materials a party relies on in a motion — deposition excerpts, interrogatory answers, admissions, or produced documents — to come with proper authentication: a certification from the deposition officer, an original or copied signature on discovery responses, or a certificate of authenticity for produced documents. A court deciding a motion can consider only material that meets these requirements, was properly presented under Rule 43.01 or 43.02, or was stipulated by the parties — a limit that matters most in summary judgment practice, where the record the court may consider is tightly defined.
Frequently Asked Questions
Can a witness testify at trial by video instead of appearing in person?
In limited circumstances. Rule 43.01 allows remote audiovisual testimony on a showing of good cause, compelling circumstances, and adequate safeguards, with a stricter standard for party and expert witnesses than for ordinary lay witnesses, and specific deadlines for filing and ruling on the motion.
Who pays for the technology if a witness testifies remotely?
The party offering the remote testimony. Rule 43.01 makes that party responsible for the equipment, logistics, and cost of the remote setup, and a technical failure on that party’s end is not grounds for a continuance.
Can a motion be decided without live testimony?
Yes. Rule 43.02 lets a court decide a motion based on affidavits alone, though the court can direct that some or all of the matter be heard through live testimony or depositions if it decides that is necessary.
What has to accompany documents I attach to a summary judgment motion?
Proper authentication. Rule 43.04 requires deposition excerpts to include the officer’s certification, discovery responses to include a signature, and produced documents to include either the production request and response or a certificate of authenticity.
Advisory Commission Comments [1991].
The first section [43.01] is amended to cross-reference the Tennessee Rules of Evidence. The second section [43.02] was formerly numbered 43.05. Original 43.06 on compensating interpreters is moved to Rule 54.04(3). All other sections in the original rule are deleted because inconsistent with or superfluous in light of the Tennessee Rules of Evidence.
