Simple assault, aggravated assault, and what elevates a charge
Simple assault — causing or attempting bodily injury — is generally a second-degree misdemeanor, dropping to a third-degree misdemeanor for a fight entered by mutual consent. Aggravated assault is a different world: a second-degree felony for bodily injury with a deadly weapon or against protected classes like police officers and teachers, and a first-degree felony — up to twenty years — for causing or attempting serious bodily injury, meaning injury that risks death or causes permanent impairment.
The gap between those gradings is where these cases are fought. A bar-fight punch charged as first-degree aggravated assault rests on the claim that the defendant attempted serious bodily injury — an element the Commonwealth must actually prove, and one that frequently cannot survive a contested preliminary hearing. Strangulation deserves particular attention: it requires no visible injury at all, and jumps from a misdemeanor to a second-degree felony in domestic contexts and a first-degree felony when a protective order was in effect. Robbery, terroristic threats, and recklessly endangering another person round out the charges most often seen alongside assault counts.
Self-defense in Pennsylvania
Pennsylvania law justifies force a person reasonably believes immediately necessary for protection, and deadly force against threats of death, serious bodily injury, kidnapping, or forcible sexual assault. There is no duty to retreat in one's home or workplace.
Just as important is who carries the burden. Once any evidence of self-defense enters the case — from any witness, including the Commonwealth's — the prosecution must disprove it beyond a reasonable doubt. The defendant never has to prove justification. That makes early investigation decisive: 911 audio from both sides, photographs of the client's own injuries before they fade, surveillance video before it is overwritten, and scene geometry all become the raw material of a justification defense.
When the complainant wants to drop the charges
In Pennsylvania, the Commonwealth — not the complainant — controls the prosecution. A complainant cannot withdraw charges; only the District Attorney can. Prosecutors regularly proceed without a cooperating complainant, using 911 recordings, photographs, medical records, body-camera footage, and other witnesses. A recantation creates proof problems, but it does not end the case — and no-contact bail conditions remain fully enforceable while the case is open, which is something families need to understand early and clearly.
