Resid'l Income Property. Buyer filed complaint [Specific Performance] against Seller/D. Can they prevail with all the irregularities listed below?

Listing agent was a Dual Agent. Plaintiff's/B dates listed in the complaint are inaccurate. Offer presented to Sellers/D on the 12th, on the 14th (2 days later) Seller/D accepted offer. Dual Agent lists the offer as being accepted and forwarded to Buyer/P on the 20th. I have proof it was accepted on the 14th, and I KNOW Dual Agent informed Buyer/P of the acceptance on the 14th. That same day listed as Agent notifying Buyer/P of acceptance, Agent started emailing "Buyer backed out, have another offer for 35,000 more than the Buyer's offer!" The Buyers did not officially back out (I guess) because 16 days later, Buyer and Dual Agent performed visual inspection. Plaintiff/B had material breached: 1.) Earnest money dept. was 10+ days late (Dual Agent nor Escrow Agent informed the Seller/D of late dept. After escrow was 25+days late, no extensions filed, Seller/D requested escrow sent out cancels. Buyer refused to sign several mnth later Seller received warning, 2 mths later complaint filed
