no
but its usually better to apply again than appeal, and make sure what ever reason they refused your visa app for the first time, you show that you've dealt with that problem in your new visa app
i don't know what the refusal rate is for ILR, but i wouldn't have thought it was high, as you've already successfully appiled for a spouse visa, as long as your provide the evidence they ask for.Also make sure you send your ILR as soon as you are able to, if it is refused, then you have time to reapply before your spouse visa expires.
