Three voters in Hulu Selangor have filed for judicial review in the Kuala Lumpur High Court seeking to quash the Election Commission's (EC) exercise in altering the constituency boundary that they claim have affected them.

They are asking the court to declare that EC's nationwide locality correction exercise, which was gazetted on April 29 and caused a huge number of voters being shifted out their previous polling station, as unconstitutional and illegal.

The applicants - P. Maradeveran (59), Zahar Rusuli (49) and Yong Chan Hee (36) - claimed to have been affected by the delineation exercise, which also involved Kuala Kubu Bahru (KKB) state seat and its adjacent state constituency - Batang Kali.
