U.S. District Judge Charles R. Richey indefinitely recessed Southern Pacific Communications Co.'s month-old antitrust trial against American Telephone & Telegraph Co. yesterday.

The move came after a day-long hearing in which AT&T's lead lawyer, George Saunders, urged the judge to dismiss the case, arguing that it had no merit. SPCC had finished presenting its case--in which it is seeking $564 million in damages from AT&T--last week and AT&T had been scheduled to begin its defense next Monday.

However, Richey postponed that date indefinitely, pending his ruling on AT&T's dismissal request.

In recessing the trial, however, Richey said he may not decide to delay a decision on AT&T's request until after the Bell System presented its defense.
