Was de Leon a Student of Paras?

In page 240, Comments & Cases on Partnership, Agency, & Trusts, 2010 Ed., the authors gave the following example to explain Article 1834:

Why the switch from D to X? My take is that the authors, while in law school, must have cut their legal teeth on the textbook of Paras.

Here's the explanation of Paras for the same article, from page 717 of Civil Code of the Philippines Annotated, Vol. V, 2008 Ed.

Mistaken Identity

From the Comments and Cases on Partnership, 2010 Ed., by de Leon:

Page 445.

Let's simplify. Pedro sold oxen to Tonyo indirectly because Tonyo wouldn't have anything to do with Pedro. Tonyo returned the oxen upon learning of the malevolent provenance of the oxen.

Methinks that the issue should be whether Pedro has the right to retain the purchase price. On page 446 the author recovers his bearings by correctly saying no.

Page 497

Tonyo (again?) paid Pedro through Ambo, Pedro's collector. Now, who should be turning over the collection to Pedro. Tonyo? Or Ambo? You tell me.

Page 607.

Ambo borrows money from Pedro. Pedro tells Ambo that Ambo can get Pedro's horse if Pedro does not pay.

Wait a minute, I thought Ambo was the borrower.

Self-serving

First, someone borrows from oneself. Page 401, Comments and Cases on Obligations and Contracts, 2010 Ed., by De Leon:

Next, he sells to himself.  Page 120, same book:

Then he paid to himself.  Page 495,  Comments and Cases on Partnership, Agency and Trusts, 2010 Ed., by de Leon.

(See the bonus typo.)

 Finally, after so much confusion, she ejects her own self. Page 676, same book:

The Descent of Man

I have an old edition of this book.It chronicles the progress of the human race from the primitive to the modern man.  Highly recommended.

But on page 688 of the Civil Code of the Philippines Annotated, 2008 Ed. we may have a contrary opinion. :-)

Sex Change

This one, feminists would love.

From page 823, Civil Code of the Philippines, Annotated, Vol. 5, Special Contracts,   2008 Edition by E. Paras:

 

Update Oct 15, 2012: On the other hand feminists would ask, "why not the diligence of a good mother."
