Fracking supporters want an investigation of whether a celebrity antifracking group started by Yoko Ono and her son, Sean Lennon, is violating New York’s lobbying law.

Artists Against Fracking failed to register as lobbyists, the Independent Oil & Gas Association says.

Registration would require the group to make disclosures about its spending and lobbying activities.

The association, which backs fracking as a way to extract natural-gas deposits upstate, filed its complaint with the state Joint Commission on Public Ethics.

A spokesman for Artists Against Fracking says it’s not required to register because it spoke against fracking during a public comment period on the state’s proposed fracking rules.
