América rescue a draw against Necaxa through a VAR penalty: the debate over Law 12 and the VAR intervention threshold

A free kick is swung into the penalty area. Julián Carranza turns and swings a boot to clear, and the ball strikes his arm. Referee Guillermo Pacheco Larios does not blow his whistle. Play runs on. No player raises a hand, no shout comes from either bench. Then the earpiece crackles. VAR calls.

I watched América against Necaxa on Jornada 10 of the Liga MX Apertura 2026 alone in my apartment in Shenzhen, lights off, the screen the only source of light. It is a habit I have kept through years of following Mexican football deep into the night. The moment the VAR team summoned the referee to the monitor, I knew the match had changed hands. The decisive moment here was not a piece of play but a reading of the law. Pacheco Larios reviewed the images, pointed to the spot, and América equalised inside the first half, while Necaxa lost two points they believed were safely banked.

The context matters. América went into Jornada 10 under Guillermo Almada, the club with the heaviest media footprint in Liga MX. Necaxa are far smaller in market size, in support and in media weight. The free kick that produced the controversy belonged to Almada's side. From that set piece, the ball travelled into the box, Carranza cleared it, and it touched his hand.

What struck me as someone tracking this match: beyond the description of the incident, almost no data travelled with it. No expected goals, no possession share, no pass counts, no set-piece breakdown. A whole match is being judged by one instant. And when a match is reduced to a single event, that event will be dissected down to the bone.

So what is actually being argued here?

On the law. Law 12 of the IFAB Laws of the Game does not outlaw every contact between ball and arm. There are two doors through which an arm contact becomes an offence: the player handles the ball deliberately, or the arm is positioned so that it makes the body unnaturally bigger relative to the body's natural movement. Pacheco Larios chose the second door. He concluded that Carranza's arm was in an unnatural position.

Francisco Chacón, a former referee now working as an influential analyst in Mexico, accepts that the ball touched the arm but rejects that conclusion. In his view the action lacked deliberation. He then pushed the argument to another level entirely: in his reading, it looked more like a foul by the player named Henry for dangerous play than a penalty. He also stressed that on the field nobody, absolutely nobody, had seen or claimed anything at all.

That last detail is where the law bites. The IFAB VAR protocol permits intervention only for a clear and obvious error or a serious missed incident. The video referee is not licensed to re-referee a match for marginal, ambiguous or heavily subjective calls. Chacón used the silence on the pitch to argue in reverse: if nobody saw it, then the error was not clear and obvious enough for VAR to call.

A technical detail is worth pausing on. The match did not stop immediately. The ball kept rolling, the players kept running, and only after the VAR review did play get cut. That interval is not meaningless. It is evidence that the incident did not incriminate itself.

The second point is heavier. If an offence by the attacking team occurred before the ball struck the arm, the penalty cannot stand. Chacón named Henry and dangerous play. That is a legal hypothesis capable of reversing the entire decision, not a footnote. As of writing I have seen no public document confirming whether the authorities reviewed the preceding passage of play.

There is one passage I must separate out, because it belongs to opinion rather than evidence. Chacón referred to VAR official Camacho Peregrina sharing a padel club with Elizondo. I record that as a personal remark. No public document in my possession shows any wrongdoing, improper acquaintance or opaque intervention. I forge opinions on the anvil of data and swing the hammer plainly, but the hammer only falls when there is something to strike. Here there is not.

The word robo is being thrown around heavily on social media. It is slang, it is emotion, and it carries no legal weight. But it reflects something real: public faith in the officiating system is being worn down round by round.

And this is where I want to move against the crowd. When the whole world looks one way, I open the door nobody thought to knock on. The direction the majority are staring at is the position of the arm. The direction I want to examine is the intervention threshold.

If Carranza's arm really was in an unnatural position, and that may well be true, then Pacheco Larios's decision holds up technically. But a correct decision does not automatically make the intervention correct. Those are two different questions under two different standards. Nobody on the pitch reacted, including the assistant referee standing closest. A clear and obvious error that no match official on the field could see needs something sturdier than the feeling of a man sitting in front of a monitor.

I may be wrong. I may be wrong in that the handball law was written precisely to hand referees discretionary judgement, and in demanding a higher intervention threshold I am demanding something the law never promised. IFAB has rewritten the handball criteria several times since 2026, and each rewrite produced a fresh grey zone. In the expected-goals series I wrote during the pandemic, I dug back into the 2026 Champions League final and found Bayern Munich generated an overwhelming volume of expected goals yet still lost to Chelsea. Results conceal process. But the story here sits one layer deeper: the result is not concealing process, it is concealing a human decision. Those two kinds of concealment should not be equated.

It is also worth being blunt about the big-club favouritism frame. It is an unfalsifiable argument. América are the biggest club in Mexico, so every decision involving them gets amplified. We remember the calls that go a giant's way and forget the ones that go against them, because the latter generate no content. I am no prophet. I only look three steps ahead of the dance of chaos, and the first step of this dance is pressure falling on two men: Pacheco Larios and Camacho Peregrina.

For Necaxa, a dressing room has lost two points in a situation it could not control. For América, a draw arrived from the penalty spot, and the pressure on Almada has not eased because of it. Mexican football has a trait I have observed for years: refereeing controversies here do not end when the final whistle goes, they simply change venue, from the pitch to the studio desk.

Three checkable predictions for the coming weeks. Liga MX and the FMF are unlikely to publish the VAR audio from this incident. Pacheco Larios is unlikely to be appointed to América matches for the next two or three rounds, even without any disciplinary announcement. And the handball criteria will return as a flashpoint later in the Apertura 2026, next time in a different match, with a different club and a different referee.

I do not write to persuade. I write to unlock your imagination.
