David Cameron will promise a crackdown on "time wasting" legal challenges to Government policies, such as planning decisions, as part of his efforts to boost economic recovery.
In a speech to business leaders at the CBI annual conference, the Prime Minister will announce plans that will see opponents given less time to apply for judicial review, face higher fees and see the chances to appeal halved.
Mr Cameron will say he is determined to "get a grip" on the process after the number of applications almost trebled in a decade.
Downing Street said they were aimed at making people "think twice about time-wasting" after application numbers rose from 160 in 1975 to 11,200 last year.
