@akhila13 return false does not work in onSubmit() GlideAjax as it makes a async call to server.

There is a ServiceNow KB article which helps you to achieve this.

ga.addParam('sysparm_name', 'canResolveIncident');
ga.addParam('sysparm_state', g_form.getValue('state'));
ga.addParam('sysparm_group', g_form.getValue('assignment_group'))
ga.getXML(setState);
function setState(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
g_form.addInfoMessage(answer);
// g_form.addErrorMessage("test");
//retrun false;
if (answer == 'Cannot Resolve') {
g_form.addErrorMessage("Cannot change the state to resolved");
return false;
}
else {
g_scratchpad.isFormValid = true;
g_form.submit();

You have missed :

var actionName = g_form.getActionName();

and 

g_form.submit(actionName);
