Does the restriction against a public official from appearing as counsel on a matter he intervened when he was in government temporary? Explain.

No. The restriction against a public official from using his public position as a vehicle to promote or advance his private interests extends beyond his tenure on certain matters in which he intervened as a public official. Rule 6.03 makes this restriction specifically applicable to lawyers who one held public office. A plain reading of the rule shows that the interdiction (1) applies to a lawyer who once served in the government, and (2) relates to his accepting “engagement or employment in connection with any matter in which he had intervened while in said service.” (PCGG vs. SB, et al., supra.).
