double ては in a sentence

Question

「……そも、この学園にはその軋みがないものね。術式めいてはいるだけでは何も起きる訳がない、か」

In this school there are no such conflicts.

And I really have no idea bout the second part.

Can someone explain it to me?

Added fantranslation of the bold sentence:

With nothing but empty ceremonies nothing ever happens, i guess.

My understanding from following Naruto's advice of removing the second は brings me to this translations.

Just because there are ceremonies does not mean that nothing happen.

Answer 1

There are two は in the second sentence, which looks unnatural to me. The author should have wanted to write either:

• 術式めいてはいるだけで、何も起きる訳がない、か
  It only resembles magic; there's no way something can happen, huh?

• 術式めいているだけでは、何も起きる訳がない、か
  Just because it resembles magic doesn't mean something can happen, huh?

• noun + めく forms a literary verb which means "look like ～", "resemble ～". It happened to be asked very recently in this site (see this question).
• I'm not sure if ceremony is the right word for 術式. 術式 in such a context usually refers to magical procedure, magic circle, etc.
• ～わけがない is "There's no way ～", "It's impossible that ～".
  • 何も起きるわけがない = No way something can happen; Nothing can happen
