In 2369, Kaval served as the Minister of State in Bajor's newly formed Provisional Government. After Aamin Marritza was arrested aboard Deep Space 9, and evidence of his presence at Gallitep was discovered, Kaval contacted Commander Benjamin Sisko and congratulated him for imprisoning Marritza, telling him he had performed a "special service" for Bajor. Though Sisko argued that Starfleet did not have grounds for holding the Cardassian, Kaval bluntly replied "we will have him".
The script for "Duet" provides the pronunciation of Kaval's name as "ka-VAL". 
In the Star Trek: Deep Space Nine Mission Gamma novel Twilight, Kaval still serves as Minister of State for Bajor in the year 2376. In that year, the character Charivretha zh'Thane believes Kaval may be involved in negotiating the agreement for Bajor to send katterpod shipments to Europa Nova.
