What follows is an opinion from a United States Court of Appeals. Your task is to identify what party initiated the appeal. For cases with cross appeals or multiple docket numbers, if the opinion does not explicitly indicate which appeal was filed first, assumes that the first litigant listed as the "appellant" or "petitioner" was the first to file the appeal. In federal habeas corpus petitions, consider the prisoner to be the plaintiff.

Opinion:
PARELMAN v. PARELMAN.
No. 11732.
United States Court of Appeals District of Columbia Circuit.
Argued Nov. 18, 1953.
Decided Feb. 4, 1954.
Mr. J. E. Bindeman, Washington, D. C. , for appellant. Mr. Theodore Klig-man, Washington, D. C., entered an appearance for appellant.
Mr. Albert E. Brault, Washington, D. C., with whom Mr. Denver H. Graham, Washington, D. C., was on the brief, for appellee.
Before WILBUR K. MILLER, BAZE-LON and WASHINGTON, Circuit Judges.
PER CURIAM.
In this suit a mother charged her son with negligence which she alleged was the proximate cause of personal injuries sustained by her, for which she sought damages in the sum of $25,000. The mother complains on appeal that the trial judge erred in directing a verdict for the defendant at the close of her counsel’s opening statement to the jury.
We think the judge correctly concluded, from what the plaintiff’s counsel said he expected to prove, that a cause of action had not been stated.
Affirmed.
