1. there is no such inquiry under the CPC
2. the respondent in both your applications has to file his reply with supporting documents and then matter will be posted for hearing on your applications, provided you are granted liberty to file a rejoinder or the respondent is permitted to file his sur-rejoinder to your rejoinder
3. for the 7/11 application, if suppose the plaint is said to be barred by law, for instance under limitation law, then applicant can adduce evidence and be cross-examined on that by the respondent. Similarly respondent can file his affidavit of evidence to prove that plaint is not barred by limitation and applicant will get a chance to cross examine the respondent to impeach his crediblity
4. the court will after appreciating the evidence of the parties, the materials available on record and documents, decide whether the application should be allowed or not
5. so as such there cannot be any inquiry under both such applications and the same is also not contemplated in the CPC
