0–9

12.44 Reduction

A state jail felony punished as a Class A misdemeanor under Tex. Penal Code § 12.44. Subsection (a) retains the felony conviction with misdemeanor-level punishment; subsection (b) requires the prosecutor's consent and produces an actual Class A misdemeanor conviction — a difference that matters for firearm rights and future enhancement exposure.

See also: 3g Offenses

A

Adjudication

In Texas deferred adjudication cases, the entry of a finding of guilt that converts the deferred status into a conviction. Adjudication occurs only after a successful motion to adjudicate or by the court's entry of guilt at the original plea proceeding.

See also: Texas Probation Deferred Adjudication · MTA Procedure

Affirmative Defense

A defense the defendant must prove by a preponderance of the evidence, such as duress or the Romeo-and-Juliet age defense. Tex. Penal Code § 2.04 places that burden on the accused once the issue is raised; the State always retains the burden of proving the offense itself beyond a reasonable doubt.

Aggravated Robbery

In Texas, robbery (theft accompanied by violence or threat) involving a deadly weapon, serious bodily injury, or a victim 65+ or disabled. First-degree felony under Tex. Penal Code § 29.03. Excluded from judge-recommended probation but available for jury-recommended probation.

See also: 3g Offenses

Alibi

A defense that the defendant was elsewhere at the time of the alleged offense and thus could not have committed it. Texas and federal courts have specific notice requirements for alibi defenses.

Allocution

The defendant's right to speak personally at sentencing before the court imposes sentence. Federal allocution is required by Federal Rule of Criminal Procedure 32(i)(4)(A)(ii); Texas allocution is required by Tex. Code Crim. Proc. art. 42.07.

Appellate Brief

The principal written argument filed with the appellate court. Briefs must comply with strict formatting, page-limit, and content rules under the Federal Rules of Appellate Procedure or the Texas Rules of Appellate Procedure.

See also: Appeals

Arraignment

The formal court proceeding where the defendant is informed of the charges and asked to enter a plea. Federal Rule of Criminal Procedure 10 governs federal arraignment; Texas arraignment is governed by Tex. Code Crim. Proc. art. 26.01.

Evidence favorable to the accused that is material to guilt or punishment. Under Brady v. Maryland, 373 U.S. 83 (1963), prosecutors must disclose Brady material to the defense. Failure to disclose can result in conviction reversal.

See also: Federal Defense Guide

Burden of Proof

The obligation to prove or disprove a fact. Criminal cases require proof beyond a reasonable doubt at trial; civil-related criminal matters often require proof by preponderance or clear and convincing evidence.

C

Capias Warrant

A warrant issued for the arrest of a person who has failed to appear at a court setting or who has violated probation. Texas capias warrants are commonly used in probation-violation matters.

See also: Mtr Procedure

Chain of Custody

Documentation of the chronological possession and handling of evidence from collection to presentation. Breaks in chain of custody can produce admissibility challenges.

Confrontation Clause

Conspiracy

An agreement between two or more persons to commit a crime, plus an overt act in furtherance. Federal drug conspiracies under 21 U.S.C. § 846 do not require an overt act.

Continuance

See also: Federal Defense Guide

Diversion

A pretrial program that allows defendants to avoid criminal prosecution by completing specified conditions (community service, treatment, restitution). Successful completion results in dismissal of charges.

Double Jeopardy

The Fifth Amendment prohibition on being tried twice for the same offense after acquittal or conviction. State and federal prosecutions are not double jeopardy as to each other under the dual-sovereignty doctrine.

DWI

Driving While Intoxicated. Texas DWI offenses under Tex. Penal Code § 49.04 et seq. range from Class B misdemeanor (first offense) to felony (third-or-subsequent, child passenger, DWI with injury, intoxication manslaughter).

See also: DWI Cases · DWI Penalty Calculator

E

Enhancement

A factor that increases the punishment range for an offense. Texas enhancement under Penal Code § 12.42 can elevate a felony to a higher degree based on prior convictions.

Examining Trial

A pre-indictment hearing at which a felony defendant may challenge probable cause, examine the State's witnesses under oath, and address bail. Tex. Code Crim. Proc. art. 16.01 grants the right; it ends once the grand jury returns an indictment, so the window to use it is short.

F

Franks Hearing

N

No-Refusal Weekend

O

Objection

A formal protest by counsel during proceedings, on legal or evidentiary grounds. Must be timely and specific to preserve the issue for appellate review.

Plea Bargain

A negotiated agreement between prosecutor and defendant resolving the case. Common terms: charge concessions, sentencing recommendations, cooperation, appeal waivers.

Reasonable Doubt

Reasonable Suspicion

Specific, articulable facts suggesting criminal activity — the Terry v. Ohio (1968) standard that justifies a brief investigative stop. It requires less than probable cause, and whether the officer's stated facts actually meet it is a frequent suppression battleground in traffic-stop DWI and drug cases.

Revocation

The court's decision to terminate community supervision and impose imprisonment. Texas straight probation revocation imposes up to the suspended sentence; deferred adjudication adjudication can impose any sentence within the statutory range.

See also: Mtr Procedure

S

Shock Probation

A judge's authority under Tex. Code Crim. Proc. art. 42A.302 to suspend the remainder of an eligible sentence within 180 days of execution and place the defendant on community supervision. Timing and offense-eligibility rules are strict, and the motion is addressed to the court's discretion.
