WASHINGTON, Jan. 26 — The Supreme Court today declined for the present to review the suppression of the film “Manson” during the selection of a jury in the trial of Lynette “Squeaky” Fromme.

The court rejected without comment a request by makers of the film that their appeal be heard at the same time as a Nebraska “gag order” case the justices have agreed to consider.

Miss Fromme was convicted in November of attempting to assassinate President Ford by pointing a pistol at him on the grounds of the California State Capitol in Sacramento.

She is a follower of former cult leader Charles Manson, now serving a life term in prison for a number of murders in Southern California.

She appears, along with other members of the “Manson Family,” in the documentary film.

On Oct. 17, after viewing the film, U.S. District Judge Thomas J. MacBride of Sacramento banned its showing in 26 Northern California counties until a jury had been sequestered.

MacBride said the rights of the filmmakers to freedom of expression under the First Amendment to the Constitution were “irreconcilable” with Miss Fromme’s right to a fair trial and must be subordinated.

The filmmakers told the high court that there are more than two million people in the 26 counties involved.

“The suggestion that enough of those prospective jurors would see a documentary on Charles Manson to render impossible the selection of a fair jury is startling — and wholly unsupported in the record,” they said.

The court also declined to expand its consideration of a Missouri abortion case to include the question of whether a state may deny Medicaid to women who choose to have abortions.
