Horace Gray, Louisville Company v. Wangelin…
“ It is equally well settled that in any case the question whether there is a separable controversy which will warrant a removal is to be determined by the condition of the record in the state court at the time of the filing of the petition for removal, independently of the allegations in that petition, or in the affidavit of the petitioner, unless the petitioner both alleges and proves that the defendants were wrongfully made joint defendants for the purpose of preventing a removal into the federal court. ”
