This motion is denied. The amount in dispute is less than $5,000, and we cannot discover that the decree involves the decision of any such federal question as will authorize an appeal to this court under section 2 of the act of March 3, 1885, (23 St. 443, c. 355.) An injunction restraining a person from prosecuting an ordinary suit in replevin in a court established under the authority of the United States does not necessarily involve a question of 'the validity of a treaty or statute of or an authority exercised under the United States.'
