In 2002, Jimenez charged that Devanadera went to his house to extort money.

Devanadera was appointed counsel of former Justice Secretary Hernando Perez who was held by the Ombudsman liable for graft and extortion regarding Manila Rep. Mark Jimenez's claim that Perez extorted $2 million from him. She successfully had Jimenez deported to the United States for tax evasion trial.[13]

Legal controversy
Previously, Devanadera and Antonio Nachura contested the position of Supreme Court associate justice vacated by Chief JusticeArtemio Panganiban. Devanadera's name, however, was deleted in the final list of nominees submitted by the Judicial and Bar Council to the President because of pending graft / regular administrative cases against her (Sec. 5.1, JBC-009 Rule)[23] that Ilocos Sur Governor Luis Singson filed versus Devanadera and others before the Office of the Ombudsman of the Philippines. The criminal cases cited the Anti-Plunder Act in relation to the Anti-Graft and Corrupt Practices Act and involved the Poro Point Special Economic and Freeport Zone.
