## Quick Overview

Derek Chauvin is legally entitled to a new trial because the cumulative effect of multiple errors, including improper expert testimony, the state presenting false evidence, and unconstitutional jury instructions, deprived him of his due process rights under the Sixth and Fourteenth Amendments, as argued in this legal analysis of the motion.

**Key Points:**
- The defense argues that the erroneous admission of improper opinion testimony by state experts denied Chauvin his Sixth and Fourteenth Amendment rights to a fair trial.
- The state's alleged abuse of video evidence violated Chauvin's right to a fair trial under the Sixth and Fourteenth Amendments.
- The state presented false evidence and failed to correct it, which, according to the petitioner, mandates a new trial.
- The testimony of key witnesses like Katie Blackwell, Medaria Arradondo, and Johnny Mercil is cited as false and misleading, meeting the Larrison standard for a new trial.
- The jury instructions were flawed, specifically concerning definitions related to Third Degree Assault and the requirement for a unanimous verdict, which the defense claims is unconstitutional.
- The cumulative effect of all errors, including the false testimony and improper jury instructions, deprived Chauvin of due process, warranting a new trial even if individual errors might not have been sufficient alone.
- The defense points out that the State relied heavily on the false testimony regarding training (BATES 2596 and Exhibit 17) which the MPD supervisors allegedly knew was false.

**Context:** This video analyzes the legal arguments presented in a motion seeking a new trial for Derek Chauvin following his conviction. The core of the argument centers on alleged constitutional violations by the prosecution and the trial court, specifically involving improper expert testimony, the presentation of false evidence by the State regarding police training tactics (like the knee-to-neck restraint shown in Exhibit 17), and flawed jury instructions. The speaker is reviewing excerpts from the legal filing detailing these claims.

## Detailed Analysis

The legal analysis focuses on several grounds Chauvin's counsel asserts justify a new trial, primarily centering on violations of his Sixth and Fourteenth Amendment rights to due process. Key arguments include the erroneous admission of improper opinion testimony from state experts, which the defense claims improperly influenced the jury by suggesting specialized knowledge. Furthermore, the defense highlights the State's alleged abuse of video evidence and the presentation of false testimony regarding whether Chauvin was trained on the knee-to-neck tactic (referenced in Bates 2596 and Exhibit 17). The State allegedly knew this testimony was false but failed to correct it, a violation the petitioner argues mandates a new trial based on Supreme Court precedent regarding the presentation of known false evidence. The argument also critiques the jury instructions, asserting they contained material misstatements of law concerning Third Degree Assault and that they permitted a non-unanimous conviction, which violates constitutional standards. The cumulative effect of these errors, even if individual errors were deemed minor, is argued to have fatally infected the trial, warranting a new trial where new evidence regarding the training (like the sworn statements from former MPD officers) can be presented.

### Argument I

- Erroneous Admission of Improper Opinion Testimony: Denied Chauvin's right to a fair trial under the 6th and 14th Amendments
- State experts denied Chauvin's right to a fair trial and due process
- Courts use caution with expert testimony to prevent jury influence.

### Argument II

- State's Abuse of Video Evidence: Violated Chauvin's right to a fair trial
- State presented false evidence and failed to correct it, meaning Chauvin must be granted a new trial
- US Supreme Court precedent on known false evidence incompatibility with due process.

### Argument C

- Testimony of Tobia and State Experts: Testimony was highly prejudicial and led to an outcome based on false premises
- Expert testimony was not probative on medical consequences
- State relied on flawed medical/video analysis regarding cause of death.

### Section A

- False and Misleading Testimony Offered by Katie Blackwell, et al.: False testimony offered by Blackwell, Arradondo, and Mercil meets the Larrison standard for a new trial
- All three prongs of the test satisfied
- Testimony was taken by surprise or known to be false after trial.

### Section B

- Effect of Improper Testimony: Pervasive throughout the trial
- Testimony failed helpfulness test and usurped the jury's role
- Specific examples cited regarding training and MPD policy.

### Section VI

- Jury Instructions Violated Due Process: Errors in instructions on Third Degree Assault and Attempt
- Instructions permitted conviction on an 'attempt to attempt' to inflict harm, which is an unconstitutional jury instruction.
