Before the adoption of the by-laws of October, 1900, defining specifically what should constitute a broken leg, there was no definition or regulation governing this matter, as we understand the record; and it is conceded that, if the plaintiff is not bound by this enactment, he is entitled to recover. The plaintiff’s action is based upon the certificate issued to him by the defendant, and it is the contract upon which his rights against the defendant must rest, and by which the liability of the defendant must be measured. The certificate which the plaintiff accepted as his contract with the defendant provides that “the articles of incorporation, fundamental laws, by-laws, rules, and regulations * * * now in force, or which may be hereafter adopted, shall together constitute the exclusive contract” between the parties.
*694It is, of course, elementary that parties competent to . i. Aftee en-fawí e&cct of' contract may make such contracts as they J J see fit, so long as the public is not injured thereby, and that courts will do no more than to'construe them as they find them, regardless of the consequences to either of the contracting parties. It is argued .that the bj'-law under consideration is unreasonable, and therefore does not bind the plaintiff. , But the language of the contract is broad, and clearly and expressly provides that future by-laws and rules and regulations shall constitute a part thereof. We know of no. reason why parties may not contract to be bound by future-enactments, and that such enactments may enter into and form a part of their contracts; but, on the other hand, we-believe it to be the general holding that they may.

But if it be conceded for the purposes of this case that changes in by-laws under such an agreement, can only be reasonable, we think the change here should be held valid. „ nessfbrok'en leg: definition A mutual association of this kind is for the-benefit of a great number, and its affairs mug£ conducted for the greatest good of the greatest number, and its internal affairs must of necessity be governed very largely by its proper officers without interference by the courts, and we should not hold by-laws unreasonable which have been expressly consented to in advance, except upon the clearest and most satisfactory showing. There was no previous design-*695atiou as to what a broken leg meant, and it may have been necessary for the proper protection of the great body of members .to certainly define what it did mean under the terms of the certificates, and we think such action was not unreasonable. What has already been said is sufficient to show that the defendant had no vested right in his certificate which could not be changed by the agreement lie entered into. It may be doubtful whether a change in a by-law after an injury had been received could- be made to affect the right to recover, but we do not determine the question becaüse it is not in this case.
It is contended that the new by-law is not retroactive. This may be conceded, and, if we were asked to apply it to a case of injury before its enactment, we are inclined to think the contention' sound; but the by-law clearly says what shall be deemed a broken leg after its enactment, and, as the plaintiff’s injury was in fact received thereafter, and when it was in force, it is clear that it was intended to and does apply to his case.
