Super League chief executive Robert Elstone is frustrated with Catalans signing controversial character Israel Folau.
Folau has signed a one-year deal with the Dragons after being sacked by Australia Rugby in December for writing homophobic posts on social media in April.
Elstone said: “Super League deplores the homophobic comments Israel Folau has made in the past, which squarely contradict our sport’s core values.
“I have sought the opinion of informed voices connected to our game, and the majority share my disappointment that one of our clubs has chosen to sign him.
“There is a strong feeling that the decision to sign him lets down many people connected to our sport. I made Catalans Dragons aware of those views.
“However, Super League does not have the authority to veto the registration of players and is satisfied by the due diligence carried out by The Rugby Football League.”
