In defence of the no-fault stand-down, many employers would stand down an employee under serious allegation.
Imagine the CFO of a company is accused of sexual harassment in the workplace; does anyone think that company is going to be happy with him continue his regular job, as if nothing has happened, whilst those accusations are assessed?
Especially if those claims cannot be rapidly dismissed, because the accusation does not make it to trial unless it is believed there is a genuine case.
You even had the ASIC and Australia Post bosses stand down / pay back monies recently due to the public backlash on the way they were spending taxpayer's money. None of them technically did anything illegal and yet their jobs were untenable.
That's the point of the no-fault stand-down, as others have said, to allow the employer to sideline the scandal whilst it is being investigated.
And specifically in respect to De Bellend, whilst I don't know if he's guilty or not, he's stupid enough to put himself in this position and it's all of his own making. Consensual or not, it is a fact that he was rooting a young lady WITH his mate whilst his pregnant partner was at home. Unbelievable - I mean, have all the group sex you want if you are 25, wealthy and built like a brick house, but don't get married and father a child at the same time mate.
