Three questions have been discussed in argument:

First—Does the plaintiff exist as a corporation under the name of “Pacific Bank?”

Second—Is the defendant in a position to question the corporate existence of the plaintiff?

Third—Do the Bevenue Laws of the United States require a waiver of “ presentation and demand, notice of non-payment and protest for value received,” written upon the back of a promissory note by an indorser, to be stamped ?

The first question involves the power of the Legislature to change the name of a corporation by special statute, it being claimed that the power is denied by the thirty-first section of the Fourth Article of the Constitution, which provides that “ corporations may be formed under general laws, but shall not be created by special Act, except for municipal purposes.” The mere changing of the name of a corporation is not, as it appears to us, the creation of a corporation in the sense of the Constitution. As suggested by counsel for the plaintiff*, it would seem that the changing of the name of a corporation is no more the creation of a corporation than the changing of the name of a natural person is the begetting of a natural person. The Act, in both cases, would seem to *541be what the language which we use to designate it imports —a change of name, and not a change of being. But it is unnecessary to decide this point for any purpose of the present case, for under the rule in Dannebroge Mining Company v. Allment, 26 Cal. 286, and Rondell v. Fay, 32 Cal. 354, the defendant ivas not in a position to make it. There is no pretense but that the plaintiff is “ claiming in good faith to be a corporation under the laws of this State, and doing business as such corporation” under the name of “Pacific Bank.” Such being the case, neither “its due incorporation” nor “its right to exercise corporate powers” can “be inquired into collaterally in any private suit to which it is a party.” Such inquiry must be had at the suit of the State, for so the statute expressly provides. (Stats. 1862, p. 110, Sec. 6.) Under the operation of this statute it is only necessary for a corporation, in order to establish, if controverted, its capacity to sue, to prove that it is a corporation de facto claiming in good faith to be a corporation, and to do business as such under the laws of this State. It is said, however, upon the part of the defendant, that this statute was not intended to affect corporations to be created after its passage, but only such as were then in existence; and hence, that it cannot be invoked by the plaintiff, which has been created since its passage. We see no grounds for such a construction. The statute is an amendment to a general statute concerning corporations passed in 1850, and necessarily affects all corporations which are formed, or intended to be formed, under the laws of this State. There is nothing in its language indicating an intent to confine its operation to existing corporations, nor is there anything in the reason upon which it is founded suggestive of such a limitation. We find nothing which indicates that it was intended as a curative statute merely— to heal existing infirmities only. Had such been the sole object, the Legislature would not have passed it as an amendment to a general law, which was an existing and continuing law upon the general subject of corporations, and the mere fact that it was so passed is conclusive that it was designed, *542like the statute of which it became a part, to have a prospective operation. That it was intended as a rule for future corporations there can be no question. The only doubt which could arise in this connection, would be as to whether it was intended or is to be construed as acting retrospectively —that is to say, upon corporations already formed. The case of Harris v. McGregor, 29 Cal. 124, cited by counsel, lends no countenance to the idea that corporations formed after the passage of the statute are not within its purview. This statute was not in that case, nor was any reference made to it. Neither of the parties was a corporation, nor did either party claim under a corporation. The plaintiffs were natural persons, and sued the defendants, who were natural persons, for damages caused by an alleged diversion of water by the defendants from the plaintiffs’ ditch or canal. To defeat a recovery, the defendants undertook to prove that the ditch was not the property of the plaintiffs, but of a third party, to wit: a corporation known as the Bunker Hill Canal •and Mining Company. For the purpose of proving the existence of such a corporation they offered in evidence what purported to be a certificate of incorporation, which was objected to by plaintiffs as fatally defective; the Court, however, held it to be valid. No attempt was made to prove a de facto corporation within the purview of the statute, for the Court held that the certificate was sufficient, and, therefore, ¡moved a corporation de jure. On appeal we held that the certificate, as such, was fatally defective, and did not, therefore, prove the existence of the corporation. If it could have been done, in view of the fact that the corporation was not a party to the suit, no attempt or offer had been made to obviate the defects in the certificate by proof of a de facto corporation within the meaning of this statute, hence no question did or could arise as to the effect of the statute.

The waiver of presentation, demand, notice of non-payment, and protest was not a contract within the meaning of the laws of the United States requiring a stamp. The statute requires a promissory note to be stamped, but so far as *543we have been able to discover, there is no provision requiring a transfer of a promissory note to be stamped. The contract between the plaintiff and defendant related to the transfer of the note in suit, and the nature of the transaction, in view of the Stamp Act, is unaffected by the mere terms in which the transfer is made.

Judgment affirmed,
