The key word is transparency!
Not every little decision needs to be sent to all clubs, but fairly major ones like this do.
If LK had told the clubs there would be a tender process for the travel and that one of the businesses entering the process was A) Owned by a referee, technically an employee and B) LK was a stakeholder or was in negotiations to be a stakeholder, then the clubs rightly could have called him out on it before it was awarded. The fact it was concealed is fairly serious and won't bode well in that Supreme Court action.
It's actually pretty ludicrous that LK would even sniff around a deal such as this.
Now it just leads to more speculation about if he's got any more deals on the go.
Sure, he's the owner and really the NBL as an individual. If part of the arrangement of the league is that all teams must use LK travel agents, and stay at LK hotels, use LK lease cars etc, then so be it. Might not win him any fans, complaints could be made, but at least it's out in the open instead of being reported in the news as a conflict of interest.
When the story broke on the eve of the finals about Novelly questioning LKs impartiality, it looked on the surface as someone trying to rake a bit of shit up, and most questioned biting the hand that feeds the league. Obviously Novelly had more information and it's really taking an unfortunate turn with stories like this. Can only imagine what else will be brought up in court. If this is the tip of the iceberg, the NBL might be the Titanic.
It's up there with the Trump tariffs idea, awarding a contract to yourself without letting your business partners know. LK is really not doing himself any favours.
