Using resolves should help you out here: (code not tested)

angular.module('app' []).config(function($routeProvider){
    $routeProvider
        .when('/needsauthorisation', {
            //config for controller and template
            resolve : {
                //This function is injected with the AuthService where you'll put your authentication logic
                'auth' : function(AuthService){
                    return AuthService.authenticate();
                }
            }
        });
}).run(function($rootScope, $location){
    //If the route change failed due to authentication error, redirect them out
    $rootScope.$on('$routeChangeError', function(event, current, previous, rejection){
        if(rejection === 'Not Authenticated'){
            $location.path('/');
        }
    })
}).factory('AuthService', function($q){
    return {
        authenticate : function(){
            //Authentication logic here
            if(isAuthenticated){
                //If authenticated, return anything you want, probably a user object
                return true;
            } else {
                //Else send a rejection
                return $q.reject('Not Authenticated');
            }
        }
    }
});
