Has anyone been refused before for mpnp nomination before and letter got nomination a 2nd time?

[tutsy50]

A close relative applied a couple of years back for mpnp and got refused because his supporter moved out of the province before nomination.
He wants to apply again after getting another nomination but doesn't have the refusal letter and file number again.
1,Should he write an LOE to that effect?
2,What should be the content of the LOE please?
Valuable contributions please ,thank you .
