"Lacking proper authority" can most certainly mean lacking the power to enforce their judgements. To remind you, I have acknowledged that if this committee does have that power, that authority (I'm using those words as synonyms), then it's not a kangaroo court in my opinion. But if there's any suggestion that the process is politically motivated or that Boris' guilt was presumed, then maybe it is a kangaroo court. I have no idea if this was a fair process, motivated by unbiased factors. I assume so because I have a reasonable amount of faith in our justice system, but I don't know this, and I don't know why some people are using this term to describe this committee. I assume they just want to publicly bring into question the authority of the court, but maybe there's more to it than that. Who knows?

It's considered contempt of parliament to shit-talk a PC.
And if being in contempt of parliament means a slap on the wrist and a 90 day suspension then I have to say this committee is lacking in any proper authority and might actually be a kangaroo court. It basically becomes more of an internal employment disciplinary process than a criminal or civil process.
