G.R. No. 19441 - Fua Cun vs. Summers

On August 26, 1920, Chua Soco subscribed for 500 shares of the China Banking Corporation at a par value of P100 per share.
He paid P25,000—the equivalent of one-half of the subscription price—and received a receipt with the following terms:

The receipt certified the payment made against 500 subscribed shares.
It specified that upon payment of the balance within 30 days’ notice, fully executed certificates for the shares would be issued.
It included a clause stating that failure to pay would subject the shares to sale by the bank for the recovery of the unpaid subscription.

On May 18, 1921, Chua Soco executed a promissory note in favor of Fua Cun for the sum of P25,000, payable in 90 days with interest at 1% per month.
He secured this note by executing a chattel mortgage on the shares, endorsing the receipt to Fua Cun.
The plaintiff, Fua Cun, subsequently took the endorsed receipt to the bank’s manager, informing him of the transaction, and was advised to await further board action.

In the meantime, Chua Soco accrued further indebtedness to the China Banking Corporation amounting to P37,731.68 due to dishonored commercial paper acceptances.
In a related recovery action for this indebtedness, the defendant bank attached Chua Soco’s interest in the 500 subscribed shares, and the receipt was seized by the sheriff.
The attachment was executed after the bank had notice that the receipt had been endorsed to Fua Cun.

Fua Cun brought an action asserting that by the payment of the half subscription price, Chua Soco had acquired an equitable interest equivalent to 250 fully paid shares.
The plaintiff sought:

A declaration that his lien on the shares, by virtue of the chattel mortgage, took priority over the bank’s claim.
An order directing the defendants to return the endorsed receipt.
Damages of P5,000 for wrongful attachment.

Holding that Chua Soco, through the partial payment, had acquired the right to 250 fully paid shares upon which the plaintiff’s lien was superior to the bank’s claim.
Ordering the return of the receipt to Fua Cun.
Awarding damages for wrongful attachment.

Whether the payment of one-half of the subscription price by Chua Soco effectively conferred upon him an equitable interest in a portion (initially considered 250 shares) of the 500 subscribed shares.
Whether the chattel mortgage executed by Chua Soco—through endorsement and delivery of the receipt—constituted a valid assignment capable of securing the debt to Fua Cun.
Whether the bank’s subsequent attachment and lien on the shares constituted a valid exercise of its rights, especially given that the attachment was made after notice of the assignment.
Whether statutory and common law principles, particularly those limiting a bank’s lien over its own stock, apply to preclude the bank’s claim over the shares in question.
