Both players are seated at the board in a standard play game, and are short of time (less than 5 minutes).

Should an arbiter intervene if he believes a touch move infringement has occured?

Yes

Slightly surprised by your answer Alex.

What happens if the arbiter is wrong?

They are still right.

Assuming there's no video evidence available, they get away with their mistake because it's impossible to prove they were wrong.

Probably not asked the right question.

Playing in a standard rating event recently, with both players short of time.

I played a move, my opponent then said adjust and adjusted one of his pieces, he then thought for 30 seconds or so and moved a different piece, and started my clock.

The arbiter then leaned across the table, stopped the clock and told my opponent that he had to move the piece he’d adjusted.

There was then a discussion where my opponent correctly said that he’d said adjust, and I said I wasn’t claiming a touch move violation.

The arbiter then restarted my clock.

I believe that the arbiter was wrong to intervene, if there was a violation I was at the board and could have claimed it myself.
By intervening the only person who was penalised was me, the last thing you need when short of time is somebody suddenly stopping your clock, fortunately it didn’t affect the final result.

I was surprised when I was told afterwards that the actions of the arbiter were correct, so would be interested in other people’s opinions.

The Arbiters manual, section 7.5.1, says

If an arbiter observes an illegal move he/she must always intervene immediately.
He/She should not wait for a claim to be submitted by a player.

But the arbiter didn't observe an illegal move.

It appears to be a slightly "no win" situation for the arbiter here. If a touch move violation HAD happened and the arbiter hadn't intervened there would likely be an equal recrimination.

Sometimes it is necessary to adjust a piece but best practice is to do so immediately after you've made your move, then there is no confusion about whether you intend to move it and you're not distracting your opponent. I've seen a few players - primarily juniors - come unstuck with this one.

So you have to consider your move while distracted by one of the pieces being in the wrong place - even if it was your opponent who just knocked it there!

Various Gufeld stories come to mind.

As you were sitting there, I would be tempted to see if you reacted in any way, before I decide whether to intervene. I acted as arbiter to help people play, not show everyone that I thought I was important.

Another thought on this would be as to whether moving the adjusted piece was a plausible if bad move.

Doing that is a breach of rule 4.2.1 - "Only the player having the move may adjust one or more pieces on their squares, ...", so it is definitely not best practice, although I'll grant you that it's a common practice that has the benefit of avoiding any risk of a touch-move claim against you.

An illegal move is quite different from a Touch Move infringement and has special status.

They are commonly confused by those who are not competant arbiters or familiar with the rules.

The most common confusion is taking account if the player making the so-called illegal move has completed the move by operating the timer.

Arbiters manual:'

"If an arbiter observes a violation of Article 4, he/she must always intervene immediately.
Arbiter should not wait for a claim to be submitted by a player."
