"On those authorities, it seems to me that in order to deprive a defendant of his recourse to arbitration a 'step in the proceedings' must be one which impliedly affirms the correctness of the proceedings and the willingness of the defendant to go along with the determination by the Courts of law instead of arbitration."
"It appears to us that that application was not a 'step in the proceedings' on the basis of the principles set out above. Thus, it did not (in the words of Lord Denning) express the willingness of Radio Design to go along with a determination of the courts instead of arbitration. On the contrary, it made it clear that the application for summary judgment was only advanced 'in the event that its application for a stay is unsuccessful'. In Merkin's words, approved by Otton LJ, the application made it clear that it was specifically seeking a stay, with the result that a step which would otherwise be a step in the proceedings namely an application for summary judgment, is not so treated."
