Tessie Eria Lambourne (born 14 July 1971) is an I-Kiribati civil servant, diplomat and politician.

[6][7] Lambourne was initially the chair of the newly formed Boutokaan Kiribati Moa party (BKM).

The others were Ruth Cross Kwansing, Lavinia Teatao Teem, Ruta Baabo Manate and former speaker Tangariki Reete.

Three Court of Appeal judges who ruled that the attempted deportation was unconstitutional were later suspended, a matter which is yet to be fully resolved.

The United Nations Special Rapporteur on the Independence of Judges and Lawyers, Margaret Satterthwaite, is concerned that the country lacks a working court system.
