change the name of "assertion_reason_form" you shouldn't implement hook_form..the name of the function thet passed to drupal_get_form shouldn't be like hook_form...it should be different.. test the following code (i didn't test it) ...and don't forget to clear the cache

  function assertion_reason_menu()
  {
      $items['assertion_reason']=array(
                    'title'=>'assertion_reason',
                    'page callback'=>'drupal_get_form',

this form submits perfectly in my drupal install - as suggested clear your cache and try

function assertion_reason_menu() {
    $items['assertion_reason']=array(
        'title'=>'assertion_reason',
        'page callback'=>'drupal_get_form',
        'page arguments'=>array('assertion_reason_form'),
        'type'=>MENU_NORMAL_ITEM,
        'access callback'=>TRUE,
    );

    return $items;
}

/**

    $form['assertion']=array(
        '#type'=>'textfield',
        '#required'=>TRUE,
        '#title'=>t('Assertion'),

    );
    $form['reason']=array(

    $form['submit']=array(

    );

    return $form;
}

function assertion_reason_form_submit($form_id,&$form_state) { 

    drupal_set_message('You are filled assertion or reason');
}
