Laws in violation of private contracts, as they amount to aggressions on the rights of those States whose citizens are injured by them, may be considered as another probable source of hostility. We are not authorized to expect that a more liberal or more equitable spirit would preside over the legislations of the individual States hereafter, if unrestrained by any additional checks, than we have heretofore seen in too many instances disgracing their several codes. We have observed the disposition to retaliation excited in Connecticut in consequence of the enormities perpetrated by the Legislature of Rhode Island; and we reasonably infer that, in similar cases, under other circumstances, a war, not of PARCHMENT, but of the sword, would chastise such atrocious breaches of moral obligation and social justice.
