Cham vs. Atty. Edilberto D. Pizarro

Lao vs. Medel, 405 SCRA 227 
For a lawyer to be dealt with by the Supreme Court, the transaction entered into need not be in the performance of professional services. It can be in his private capacity.

Conflict of interest
(Pormento vs. Pontevedra, March 31, 2005)
A lawyer has to disclose to his client all the circumstances of his relations to the parties in connection with the controversy which might influence the client in the selection of counsel.
It is unprofessional to represent conflicting interests except by express consent of all concerned given after full disclosure of the facts.
Tests to determine if there is conflicting interests:
1. If the acceptance of the new retainer will require the attorney to do anything which will injuriously affect his first client in any matter in which he represents him and also whether he will be called upon in his new relation, to use against his first client any knowledge acquired thru their connection;
2. Whether the acceptance of a new relation will prevent an attorney from full discharge of his duty of undivided fidelity and loyalty to his client or invite suspicion of unfaithfulness or double dealing in the performance thereof.
Reason for prohibition
The reason for the prohibition is found in the relation of attorney and client, which is one of trust and confidence of the highest degree. A lawyer becomes familiar with all the facts connected with his client’s case. He learns from his client the weak points of the action as well as the strong ones. Such knowledge must be considered sacred and guarded with care. No opportunity must be given him to take advantage of his client’s secrets. A lawyer must have the fullest confidence of his client. For, if the confidence is abused, the profession will suffer by the loss thereof.
The prohibition applies however slight such adverse interest may be (Nakpil vs. Valdes, 286 SCRA 758).
The essence of the rule is to maintain inviolate the client’s confidence or to refrain from obtaining anything which will injuriously affect in any matter in which he previously represented him.
3. Grossly immoral conduct
Emma Dantes vs. Atty. Crispin Dantes
A.C. No. 6488, September 22, 2004
The wife complained that her husband was a philanderer, having illicit relationship with two women. He was disbarred. A lawyer must demonstrate that he or she has good moral character and should behave in accordance with the standards.

Santos vs. Tan, 196 SCRA 16
St. Louis Univ. Laboratory High School Faculty & Staff vs. Atty. Dela Cruz, A.C. No. 6010, August 28, 2006
Disbarment should never be decreed where any lesser penalty could accomplish the end desired; hence, the penalty of two years suspension was more appropriate.
A lawyer got married again after his failed marriage. He never absconded his obligations to his first wife and child. After the annulment of his second marriage, he remained celibate. He was humble enough to offer no defense save for his lone and declaration of his commitment to his wife and child. (Conjuangco vs. Palma, 438 SCRA 306; 462 SCRA 310 ).
