Terminated Job After Receiving Letter Of Appointment

I have received a letter of appointment on 09/06/15 and on 18/07/15 company told me you are rejected from your job.can they terminate me?

Assuming that the company has revoked your job offer on 18.6.2015 instead of dated 18.7.2015 which is clerical error, you can sue the company for damages because under section 5 of the contract Act, the offer cannot be withdrawn after it has been accepted.
Thanks

If you have not completed the probation period then, company can terminate you anytime without prior information.

The query lacks important information.
Is the person on probation?
When did he join the company?(He got appointment letter on 09Jun15)
He cannot be terminated by a future dated letter( a clerical error I suppose,anyway shows casual and thoughtless approach of Company HR)
If poster wants clear advice of members-kindly give additional and relevant details?
Termination during probation also has to be done with care.
You just cannot terminate a probationer with a stigma.(Due enquiry would be needed.)
If termination during probation is on basis of unsatisfactory service,it can be done,but the employee can challenge it is arbitrary.
A probationer is basically on test and if he fails the test,employer can in accordance with letter of appointment terminate him.

Dear,
As per your apportionment letter you are on probation period or not if you are on probation period then company can do it without prior intimation terminate your services.
so first of all you clear that you are on probation period or not.
