Section 376(2)(g) embodies a principle of joint liability and the essence of that liability is the existence of common intention; that common intention presupposes prior concert which may be determined from the conduct of offenders revealed during the course of action and it could arise and be formed suddenly, but there must be meeting of minds. It is not enough to have the same intention independently of each of the offender. In such cases, there must be criminal sharing, marking out a certain measure of jointness in the commission of offence; Ashok Kumar v. State of Haryana, AIR 2003 SC 777.
Corroborative evidence is not an imperative component of judicial credence in every case of rape; State of Maharashtra v. Suresh Nivruthi Bhusare, (1997) 2 Crimes 257 (Bom).
(i) Medical evidence corroborated by version of prosecutrix independent witness also in favour of the victim. No evidence of causing an unknown person a false implication at the cost of family name, conviction based on her evidence upheld; Lakha v. State of Rajasthan, 1999 Cr LJ 3418 (Raj).
(ii) Where an innocent girl of just 9 years is caught hold and raped by accused, and FIR is lodged well in time, evidence of her testimony also corroborated by medical evidence, no evidence for false implication, failure on part of investigation are not enough to deny version of prosecutrix and other corroborative evidences; Najoor Ahmad v. State of Bihar, 1999 Cr LJ 2550 (Pat).
Prosecutrix consenting to s*xual intercourse
(i) If a woman meekly submits to s*xual intercourse it would be a case of consent; State of Maharashtra v. Suresh Nivrutti Bhusare, (1997) 2 Crimes 257 (Bom).
(ii) Normally a woman would not falsely implicate for the offence of rape at the cost of her character. In Indian society, it is very unusual that a lady with a view to implicate a person would go to the extent of stating that she was raped; Madan Lal v. State of Madhya Pradesh, (1997) 2 Crimes 210 (MP).
Rape and abetment to suicide
It has been held that the concent cannot be inferred merely because co-accused was present in house at the time accused raped the victim. Neither can co-accused be convicted under section 376(2)(g) merely because victim girl allegedly stated before committing suicide that both of accused raped her; Ashok Kumar v. State of Haryana, AIR 2003 SC 777.
Rape of a minor
(i) Where a minor girl just 10 years of age raped by accused, a minor of 16 years on the date of incident, convicted and sentenced to 3 years R.I., therefore, since then many years added to his age, he cannot be even sent to an approved school under the Act and as such his conviction is maintained but sentence set aside; Bire alias Bir Bahadur Singh v. State of Uttar Pradesh, 2000 Cr LJ 87 (All).
(ii) When the prosecutrix is a minor aged below 16 years, the question of her being a consenting party to the s*xual intercourse does not arise or is of no consequence; Naresh v. State of Haryana, (1997) 2 Crimes 587 (P&H).
