From Idolatry to Conversion: Judaism and Non-Jews: Conversion: The Converted Convert::
I am a Jew by choice. What would my status be if I chose
not to continue to practice Judaism?
Part of the conversion ceremony is a commitment to keep all
of the Halachah. Once a person has done this, he or she is a
full-fledged Jew, and cannot reverse the process. A convert
who chooses not to practice Judaism has the status of a Jew
from birth who does not practice Judaism - an "irreligious
Jew".
However, this assumes that a proper commitment was made
at the time of conversion. If a convert never intended to fulfill
all of the Halachah, it could be argued that the conversion
was based on a mistaken assumption and is therefore null and
void. Evidently, a qualified Rabbi must be consulted if there is
doubt about the validity of a conversion.
