Earlier this year the Blues were dudded in Cape Town after South African officials failed to punish Shaun Treeby for knocking out Blues playmaker Piers Francis. Treeby was then suspended for four weeks.
Crusaders fans have also made mention of Glen Jackson, who played 60 games for the Chiefs, being the man in the middle for Saturday's semifinal in Christchurch, though this is a longbow to draw.
If we take our lead from the test arena, rugby's pinnacle, neutral officials are guaranteed.
The 2015 World Cup final between the All Blacks and Australia? Wales' Nigel Owens took charge. The All Blacks last test in South Africa? France's Jerome Garces had the whistle. The All Blacks last test of 2016 in Paris? England's Wayne Barnes. And on it goes.
Why should Super Rugby be any different?
Super Rugby's excuse for not having neutral officials is poor - cost cutting. If that is indeed the case, surely Sanzaar can at least dig into its pockets and folk out for seven playoff games each year. This is the time when decision-making comes under the blowtorch.
This is not to suggest Peyper, in control at Ellis Park this weekend, does not deserve his appointment. He is a professional, and his ability was clear when handling the first Lions test at Eden Park.
But, with so much now at stake, why put him and his three South African colleagues in this situation?
Organisers should at least get it right next week with Australian Angus Gardner expected to get the final.
Not everyone agrees with neutral officials. The All Blacks would have been more than happy to see Owens take charge of all three Lions tests last month. Many believe the best man should get the job.
This is also not a new issue. Jackson controlled last year's final between the Hurricanes and Lions in Wellington.
But given Super Rugby's precarious place in the sporting landscape at present, why take the risk?
If the TMO in Johannesburg makes a howler this weekend, the backlash will inevitably come.
